Description

Technical Field

[0001] This application relates to the field of optical communication technology, and in particular to a single-channel control method, apparatus, optical communication equipment, and storage medium for a silicon photonics module. Background Technology

[0002] With the rapid development of optical communication technology, the demand for high-speed, high-capacity optical communication equipment is constantly increasing. The 800GDR8 silicon photonics module plays a crucial role in optical communication networks.

[0003] Current 800G DR8 silicon photonics modules are typically designed with one laser providing two Tx (transmit) outputs. However, this design makes it impossible to disable a single Tx output by turning off laser bias; in other words, existing 800G DR8 silicon photonics modules cannot accurately disable a single Tx output without affecting the other Tx output.

[0004] Therefore, how to accurately disable a single Tx output of the silicon photonics module without affecting the other Tx output is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The main objective of this application is to provide a single-channel control method, apparatus, optical communication device, and storage medium for silicon photonics modules, which aims to accurately disable a single-channel Tx output of a silicon photonics module without affecting the other Tx output.

[0006] To achieve the above objectives, this application provides a single-channel control method for a silicon photonics module. This method is applied to a control module in an optical communication device, which further includes a heating module and a silicon photonics module. The control module is electrically connected to both the heating module and the silicon photonics module. The heating module is located in the single-channel optical element region of the silicon photonics module. The single-channel control method includes:

[0007] In response to the single-channel disable command of the silicon photonics module, the heating adjustment voltage corresponding to the minimum light output power is determined based on the current ambient temperature of the single-channel optical element area and the preset fitting model.

[0008] After adjusting the heating operating voltage of the heating module to the heating adjustment voltage, the single-channel transmission output of the silicon photonics module is disabled according to the minimum light output power.

[0009] In one embodiment, the single-channel control method for the silicon photonics module further includes: constructing a preset fitting model;

[0010] The steps for constructing the preset fitting model include:

[0011] Determine multiple heater voltage values ​​of the heating module at a preset test temperature, and the output light power of the single-path optical element region driven by each of the heater voltage values;

[0012] A power-voltage curve corresponding to the test temperature is plotted with the voltage value of each heater on the x-axis and the light output power corresponding to each heater voltage value on the y-axis.

[0013] A preset fitting model is constructed based on the power-voltage curve.

[0014] In one embodiment, the test temperature includes a low temperature, a normal temperature, and a high temperature, and the power voltage curve includes a low temperature power voltage curve corresponding to the low temperature, a normal temperature power voltage curve corresponding to the normal temperature, and a high temperature power voltage curve corresponding to the high temperature.

[0015] The step of constructing a preset fitting model based on the power-voltage curve includes:

[0016] A low-temperature relationship model is constructed based on the low-temperature power-voltage curve corresponding to the low-temperature temperature; a normal-temperature relationship model is constructed based on the normal-temperature power-voltage curve corresponding to the normal-temperature temperature; and a high-temperature relationship model is constructed based on the high-temperature power-voltage curve corresponding to the high-temperature temperature.

[0017] The low-temperature relationship model, the normal-temperature relationship model, and the high-temperature relationship model are used as preset fitting models.

[0018] In one embodiment, the preset fitting model includes a low-temperature relationship model, a normal-temperature relationship model, and a high-temperature relationship model. The step of determining the heating adjustment voltage corresponding to the minimum output power based on the current ambient temperature of the single-path optical element region and the preset fitting model includes:

[0019] Determine the current ambient temperature of the single-path optical element area, and detect whether the current ambient temperature is within a preset normal temperature threshold range;

[0020] If the current ambient temperature is within the normal temperature threshold range, then the heating adjustment voltage corresponding to the minimum light output power of the heating module at the current ambient temperature is determined according to the normal temperature relationship model.

[0021] In one embodiment, the step of determining the heating adjustment voltage corresponding to the minimum light output power of the heating module at the current ambient temperature based on the ambient temperature relationship model includes:

[0022] Determine the voltage search interval corresponding to the ambient temperature relationship model, and determine the upper and lower voltage limits of the voltage search interval;

[0023] The midpoint voltage of the voltage search interval is determined based on the average value between the upper limit voltage and the lower limit voltage. The midpoint output power that matches the midpoint voltage, the upper limit output power that matches the upper limit voltage, and the lower limit output power that matches the lower limit voltage are found from the room temperature relationship model.

[0024] If the midpoint output power is less than both the upper and lower limit output power, then the midpoint voltage of the interval is taken as the next upper limit voltage; or...

[0025] If the midpoint output power is greater than both the upper limit output power and the lower limit output power, then the midpoint voltage of the interval is taken as the next lower limit voltage.

[0026] Return to the step of determining the midpoint voltage of the voltage search interval based on the average value between the upper limit voltage and the lower limit voltage, until the difference between the upper limit voltage and the lower limit voltage matches a preset equivalent threshold, and then use the midpoint voltage of the interval as the heating adjustment voltage.

[0027] In one embodiment, after the step of detecting whether the current ambient temperature is within a preset room temperature threshold range, the single-channel control method for the silicon photonics module further includes:

[0028] After determining that the current ambient temperature is not within the normal temperature threshold range, and further determining that the current ambient temperature is greater than the upper limit of the normal temperature threshold range, then based on the high-temperature relationship model, determine the heating adjustment voltage output by the heating module at the current ambient temperature, corresponding to the minimum light output power; or...

[0029] If the current ambient temperature is determined to be less than the lower limit of the ambient temperature threshold range, then the heating adjustment voltage corresponding to the minimum light output power of the heating module at the current ambient temperature is determined according to the low temperature relationship model.

[0030] In one embodiment, the step of determining the heating adjustment voltage corresponding to the minimum light output power of the heating module at the current ambient temperature based on the high-temperature relationship model includes:

[0031] Determine the temperature difference between the current ambient temperature and the normal temperature threshold, and determine the reference high temperature corresponding to the temperature difference;

[0032] The reference high temperature is superimposed on the current ambient temperature to obtain a temperature adjustment value. Based on the high temperature relationship model and the temperature adjustment value, the heating adjustment voltage output by the heating module corresponding to the minimum light output power is determined. The model algorithm corresponding to the high temperature relationship model is as follows:

[0033] Wherein, is the minimum output light power, is the temperature adjustment value, is the heating adjustment voltage corresponding to the minimum output light power, A is the quadratic coefficient of the temperature adjustment value, b is the quadratic coefficient of the heating adjustment voltage, C is the interaction coefficient between the temperature adjustment value and the heating adjustment voltage, is the linear coefficient of the temperature adjustment value, is the linear coefficient of the heating adjustment voltage, and F is a preset constant coefficient.

[0034] Furthermore, to achieve the above objectives, this application also provides a single-channel control device for a silicon photonics module, the single-channel control device comprising:

[0035] The response module is used to respond to the single-channel disable command of the silicon photonics module and determine the heating adjustment voltage corresponding to the minimum output power based on the current ambient temperature of the single-channel optical element area and the preset fitting model.

[0036] The disable module is used to disable the single-channel transmission output of the silicon photonics module based on the minimum light output power after the heating operating voltage of the heating module is adjusted to the heating adjustment voltage.

[0037] Each functional module of the single-channel control device for silicon photonics modules in this application implements the steps of the single-channel control method for silicon photonics modules described above during operation.

[0038] In addition, to achieve the above objectives, this application also provides an optical communication device, which includes a memory, a processor, and a silicon photonics module single-channel control program stored in the memory and executable on the processor. When the silicon photonics module single-channel control program is executed by the processor, it implements the steps of the above-described silicon photonics module single-channel control method.

[0039] In addition, to achieve the above objectives, this application also provides a storage medium, which is a computer-readable storage medium, and stores a silicon photonics module single-channel control program thereon. When the silicon photonics module single-channel control program is executed by a processor, it implements the steps of the above-described silicon photonics module single-channel control method.

[0040] This application provides a single-channel control method for silicon photonics modules, enabling the disabling of a single-channel Tx output from the silicon photonics module. Specifically, the single-channel control method described in this application is applied to the control module of an optical communication device. This control module is electrically connected to both a heating module and the silicon photonics module, with the heating module located in the single-channel optical element area of ​​the silicon photonics module. Responding to a single-channel disable command from the silicon photonics module, the control module can quickly and accurately determine the heating adjustment voltage corresponding to the minimum output power based on the current ambient temperature of the single-channel optical element area and a preset fitting model. Subsequently, the heating operating voltage of the heating module is adjusted to the heating adjustment voltage, thereby ensuring that the output power of the single-channel Tx channel in the single-channel optical element area is at its minimum output power. In other words, the optical signal intensity output by the single-channel Tx channel at its minimum output power is very weak, preventing the corresponding single-channel Rx channel in the silicon photonics module from receiving a valid optical signal. Thus, without affecting the other Tx output, the single-channel Tx output is disabled by softly shutting down the optical path involved in the single-channel Tx output. Attached Figure Description

[0046] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0047] This application provides a single-channel control method for a silicon photonics module, referring to... Figure 1 As shown, Figure 1 This is a flowchart illustrating the first embodiment of the single-channel control method for silicon photonics modules in this application.

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0049] With the rapid development of optical communication technology, the demand for high-speed, high-capacity optical communication equipment is constantly increasing. The 800G DR8 silicon photonics module plays an important role in optical communication networks. However, current 800G DR8 silicon photonics modules are typically designed with one laser for two Tx (transmit) outputs.

[0050] While this design improves module integration and performance to some extent, it also introduces several challenges. Due to its structural characteristics, it's not possible to disable a single Tx output simply by turning off laser bias. In practical applications, it's often necessary to control the disabling of a single Tx output based on different network requirements and scenarios. For example, in situations such as network troubleshooting, equipment maintenance, and adjustments to specific service requirements, enabling single Tx disable allows for more flexible management and optimization of optical communication networks.

[0051] Furthermore, when implementing single-channel Tx Disable, it is also necessary to ensure that Tx off Power and Timing both meet the corresponding protocol specifications. Failure to meet these specifications may lead to signal interference, transmission errors, and other problems in the optical communication network, seriously affecting the network's stability and reliability.

[0052] Currently, existing technologies have several shortcomings in achieving single-channel Tx disable for 800G DR8 silicon photonics modules. On the one hand, there is a lack of effective methods to accurately disable a single Tx output without affecting the other Tx output. On the other hand, in the process of implementing single-channel Tx disable, it is difficult to guarantee that Tx off-power and timing meet protocol specifications, posing challenges to the normal operation of optical communication networks.

[0053] Therefore, in order to solve the technical problem that the existing 800G DR8 silicon photonics module cannot achieve single-channel Tx output disable, this application provides a single-channel control method, device, optical communication equipment, and storage medium for silicon photonics modules.

[0054] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, database system, etc., or a device capable of performing the above functions, such as a silicon photonics module single-channel control device (i.e., optical communication device). The following description uses a silicon photonics module single-channel control device as an example to illustrate this embodiment and the subsequent embodiments.

[0055] The single-channel control method for silicon photonics modules in this application is applied to the control module in an optical communication device. The optical communication device further includes a heating module and a silicon photonics module. The control module is electrically connected to the heating module and the silicon photonics module respectively. The heating module is disposed in the single-channel optical element area of ​​the silicon photonics module.

[0056] The single-channel control method for silicon photonics modules provided in this application includes the following implementation steps S10 to S20.

[0057] Step S10: In response to the single-path disable command of the silicon photonics module, determine the heating adjustment voltage corresponding to the minimum output power based on the current ambient temperature of the single-path optical element area and the preset fitting model.

[0058] In this embodiment, based on the electrical connection between the control module and the human-machine interface in the optical communication device, after receiving the single-channel disable command of the silicon photonics module uploaded by the human-machine interface, the control module responds to the single-channel disable command by immediately acquiring the current ambient temperature of the single-channel optical element area to achieve real-time monitoring of the ambient temperature of the single-channel optical element area. Next, based on the current ambient temperature and the preset fitting model, the heating adjustment voltage corresponding to the minimum output light power can be accurately obtained. This allows the heating module's heating operating voltage to be quickly and accurately adjusted to a suitable voltage (i.e., heating adjustment voltage) when disabling the single-channel output of the silicon photonics module, thereby achieving the minimum output light power and ultimately disabling the single-channel transmission output.

[0059] It should be noted that the single-path optical element area can be understood as a specific area in the silicon photonics module that is dedicated to a single laser tube. This area includes the optical elements and supporting components associated with that laser tube, and is a specific spatial range specifically used to process and transmit that optical signal.

[0060] Step S20: After adjusting the heating operating voltage of the heating module to the heating adjustment voltage, enable the single-channel transmission output of the silicon photonics module to be disabled according to the minimum light output power.

[0061] In this embodiment, when the heating operating voltage of the heating module is adjusted to achieve the minimum output light power, the heating effect of the heating module on the single-path optical element area in the silicon photonics module is precisely controlled, thereby reducing the optical power output of the silicon photonics module to a minimum (i.e., minimum output light power); next, as Figure 2 As shown, noise suppression is applied to a single Tx channel within the single-channel optical element region to obtain a stable minimum output power. Furthermore, since the optical power output of the silicon photonics module is directly related to its transmission function, when the optical power output of the silicon photonics module is at its minimum, it means that the optical signal strength of that single Tx channel is extremely weak, almost negligible. From an optical communication perspective, the corresponding single Rx channel can hardly detect a valid signal from that single channel at this time. This disables the transmission function of a single Tx channel without affecting the output of the other Tx channel, thus meeting the need for precise control of a specific single channel in complex optical communication environments and improving the management efficiency and stability of the optical communication network.

[0062] It should be noted that noise reduction only includes... Figure 2 The “mz modulation” shown represents Mach-Zehnder modulation, and Figure 2 The “Tx force squelch” shown represents the transmitted forced squelch. Furthermore, Figure 2 The "IC2signal" shown represents an integrated circuit signal.

[0063] In a single-channel Tx setup, "Tx" stands for "Transmit." A single-channel Tx refers to a dedicated channel within a silicon photonics module specifically designed to convert electrical signals into optical signals and transmit them. This channel typically includes light-emitting elements such as lasers, along with related driving circuitry and optical components. It is responsible for transmitting data as optical signals to transmission media such as optical fibers, thus enabling data transmission.

[0064] In a single Rx channel, "Rx" stands for "Receive." A single Rx channel is an independent channel in a silicon photonics module used to receive optical signals from transmission media such as optical fibers and convert them into electrical signals. This channel typically includes receiving elements such as photodetectors, as well as corresponding amplification circuits and signal processing components, responsible for receiving optical signals and converting them into electrical signals for subsequent data processing and storage.

[0065] In summary, this application provides a single-channel control method for silicon photonics modules, enabling the disabling of a single-channel Tx output from the silicon photonics module. Specifically, the single-channel control method described in this application is applied to the control module of an optical communication device. This control module is electrically connected to both a heating module and the silicon photonics module, with the heating module located in the single-channel optical element area of ​​the silicon photonics module. Responding to a single-channel disable command from the silicon photonics module, the control module can quickly and accurately determine the heating adjustment voltage corresponding to the minimum output power based on the current ambient temperature of the single-channel optical element area and a preset fitting model. Subsequently, the heating operating voltage of the heating module is adjusted to the heating adjustment voltage, thereby ensuring that the output power of the single-channel Tx channel in the single-channel optical element area is at its minimum output power. In other words, the optical signal intensity output by the single-channel Tx channel at its minimum output power is very weak, preventing the corresponding single-channel Rx channel in the silicon photonics module from receiving a valid optical signal. Thus, without affecting the other Tx output, the single-channel Tx output is disabled by softly shutting down the optical path involved in the single-channel Tx output.

[0066] Furthermore, based on the first embodiment of the silicon photonics module single-channel control method of this application, a second embodiment of the silicon photonics module single-channel control method of this application is proposed. In some feasible embodiments, the silicon photonics module single-channel control method of this application further includes step A10: constructing a preset fitting model.

[0067] Step A10 above also includes the following implementation steps A101 to A103.

[0068] Step A101: Determine multiple heater voltage values ​​of the heating module at a preset test temperature, and the output light power of the single-path optical element region driven by each of the heater voltage values.

[0069] In this embodiment, as Figure 3 As shown, Figure 3 In this context, MPD_out ADC represents the output optical power of the silicon photonics module. Figure 3 The Heater DAC Square represents the heater voltage value. Heater shift (i.e., heater temperature drift) can occur at high and low temperatures. If only the heating adjustment voltage (i.e., HeaterMin) corresponding to the minimum output light power is found based on a single temperature, the debugging time varies significantly at different temperatures. Excessive time spent searching for HeaterMin can cause the Tx disabletiming to exceed the protocol specifications. This application first determines multiple heater voltage values ​​of the heating module (i.e., the heater) at a preset test temperature, and the output light power of a single Tx in the single-path optical element area driven by each heater voltage value.

[0070] It should be noted that the preset test temperature includes at least a low temperature, a normal temperature, and a high temperature. The low temperature can be -15℃, the normal temperature can be 25℃, and the high temperature can be 85℃. The above is only one feasible implementation method in this embodiment. The preset test temperature can be customized according to application requirements.

[0071] Step A102: Plot a power-voltage curve corresponding to the test temperature, with the voltage value of each heater as the horizontal axis and the light output power corresponding to each heater voltage value as the vertical axis.

[0072] In this embodiment, a power-voltage curve corresponding to the test temperature is plotted with the voltage value of each heater on the x-axis and the corresponding light output power on the y-axis. Specifically, refer to... Figure 3 Taking the power-voltage curve at -15℃ or 85℃ as an example, with the voltage value of each heater on the horizontal axis and the output light power corresponding to each heater voltage value on the vertical axis, multiple plotted coordinate points representing the relationship between the heater voltage value at -15℃ or 85℃ and the output light power of the silicon photonics module are obtained. Next, the plotted coordinate points at multiple heaters at -15℃ or 85℃ are connected by curves to obtain the waveform diagram of the relationship between the heater voltage value at -15℃ and the output light power of the silicon photonics module, or the waveform diagram of the relationship between the heater voltage value at 85℃ and the output light power of the silicon photonics module.

[0073] It should be noted that the power-voltage curve can be a waveform diagram showing the relationship between the heater voltage at -15℃ and the output optical power of the silicon photonics module, or it can be a waveform diagram showing the relationship between the heater voltage at 85℃ and the output optical power of the silicon photonics module.

[0074] Step A103: Construct a preset fitting model based on the power-voltage curve.

[0075] In this embodiment, a preset fitting model is constructed based on the power-voltage curve. This fitting model can accurately reflect the power output characteristics of the silicon photonics module under different temperature and voltage conditions, providing a reliable basis for achieving fine control of the single-channel output power of the silicon photonics module. The preset fitting model allows for more accurate adjustment of the heating module's voltage to bring the output light power of a single Tx channel to its minimum, thereby ensuring that the single Tx output remains stably disabled.

[0076] Furthermore, in some feasible embodiments, the test temperature includes a low temperature, a normal temperature, and a high temperature, and the power voltage curve includes a low-temperature power voltage curve corresponding to the low temperature, a normal-temperature power voltage curve corresponding to the normal temperature, and a high-temperature power voltage curve corresponding to the high temperature. Step A103: Constructing a preset fitting model based on the power voltage curve further includes the following implementation steps A1031 to A1032:

[0077] Step A1031: Construct a low-temperature relationship model based on the low-temperature power-voltage curve corresponding to the low-temperature temperature, construct a normal-temperature relationship model based on the normal-temperature power-voltage curve corresponding to the normal-temperature temperature, and construct a high-temperature relationship model based on the high-temperature power-voltage curve corresponding to the high-temperature temperature.

[0078] In this embodiment, a low-temperature relationship model is constructed based on the low-temperature power-voltage curve corresponding to a low-temperature temperature, a normal-temperature relationship model is constructed based on the normal-temperature power-voltage curve corresponding to a normal-temperature temperature, and a high-temperature relationship model is constructed based on the high-temperature power-voltage curve corresponding to a high-temperature temperature. In other words, by constructing specific relationship models for different temperatures, the relationship between the heater voltage and power output of the silicon photonics module under various temperature conditions can be reflected more accurately. This allows for precise adjustment of the heating module voltage based on the corresponding models in practical applications, regardless of whether the environment is low-temperature, normal-temperature, or high-temperature, to achieve fine control of the single-channel output power and ensure that the single-channel transmit output can be stably adjusted to a disabled state at different temperatures.

[0079] Step A1032: Use the low temperature relationship model, the normal temperature relationship model, and the high temperature relationship model as preset fitting models.

[0080] In this embodiment, by constructing low-temperature, normal-temperature, and high-temperature relationship models separately and integrating them into a preset fitting model, the operating characteristics of silicon photonics modules within different temperature ranges can be comprehensively covered. Thus, in practical applications, regardless of whether the optical communication equipment is in a low-temperature, normal-temperature, or high-temperature environment, accurate analysis and adjustments can be made based on the corresponding sub-models. This fitting model enables more precise control of the single-channel output of the silicon photonics module, quickly determining the appropriate heating adjustment voltage based on the current ambient temperature, thereby ensuring that the single-channel transmit output remains stably disabled.

[0081] Furthermore, in some feasible embodiments, the preset fitting model includes a low temperature relationship model, a normal temperature relationship model, and a high temperature relationship model. The above step S20: determining the heating adjustment voltage corresponding to the minimum light output power based on the current ambient temperature of the single-path optical element area and the preset fitting model, also includes the following implementation steps S201 to S202.

[0082] Step S201: Determine the current ambient temperature of the single-path optical element area and detect whether the current ambient temperature is within a preset normal temperature threshold range.

[0083] In this embodiment, the current ambient temperature of the single-path optical element area is first determined, and it is detected whether it is within the preset room temperature threshold range. This allows for the implementation of corresponding control strategies based on different temperature conditions, thereby improving the adaptability and robustness to temperature changes when applying the fitting model.

[0084] Step S202: If the current ambient temperature is within the normal temperature threshold range, then determine the heating adjustment voltage corresponding to the minimum light output power of the heating module at the current ambient temperature based on the normal temperature relationship model.

[0085] In this embodiment, if the current ambient temperature is within the normal temperature threshold range, the heating adjustment voltage corresponding to the minimum light output power of the heating module at that temperature is determined based on the normal temperature relationship model. This allows for precise control by fully utilizing the accurate model at a specific temperature, ensuring that the output of the heating module accurately adjusts the single-channel output power of the silicon photonics module to the minimum under normal temperature conditions, thus disabling the single-channel transmission output. Simultaneously, using the normal temperature relationship model avoids uncertainties caused by temperature changes, improving the accuracy and reliability of the control.

[0086] Furthermore, in some other feasible embodiments, the above step S202: determining the heating adjustment voltage corresponding to the minimum light output power of the heating module at the current ambient temperature based on the ambient temperature relationship model may also include the following implementation steps S2021 to S2024.

[0087] Step S2021: Determine the voltage search interval corresponding to the normal temperature relationship model, and determine the upper limit voltage and lower limit voltage of the voltage search interval.

[0088] In this embodiment, the voltage search range corresponding to the room temperature relationship model is determined, along with the upper and lower voltage limits. This lays the foundation for accurately determining the heating adjustment voltage corresponding to the minimum output power. By clearly defining the search range, the search process becomes more targeted and efficient, avoiding blind searches and saving computational resources and time. Determining the upper and lower voltage limits provides boundary conditions for the search, helping to explore within a reasonable range and ensuring that the final heating adjustment voltage is within a feasible voltage range. This allows for more accurate voltage adjustment of the heating module under room temperature conditions, enabling fine control of the single-channel output power of the silicon photonics module and providing reliable data support for stably adjusting the single-channel transmit output to a disabled state.

[0089] Step S2022: Determine the midpoint voltage of the voltage search interval based on the average value between the upper limit voltage and the lower limit voltage, and find the midpoint output power that matches the midpoint voltage, the upper limit output power that matches the upper limit voltage, and the lower limit output power that matches the lower limit voltage from the room temperature relationship model.

[0090] In this embodiment, the midpoint voltage of the voltage search interval is determined by calculating the average value between the upper and lower voltage limits. This effectively subdivides the search interval, providing a scientific method for gradually approaching the heating adjustment voltage corresponding to the minimum output power. The midpoint output power, upper limit output power, and lower limit output power that match the midpoint, upper, and lower voltage limits respectively are found from the room temperature relationship model. This fully utilizes the constructed model, allowing for accurate understanding of the output power under different voltages during the search process. This method helps to more accurately determine the relative relationship between the current search position and the target minimum output power, providing a clear basis for subsequent adjustments to the search direction. It enables more precise control of the single-channel output power of the silicon photonics module under room temperature conditions, gradually approaching the ideal heating adjustment voltage within a continuously narrowing search interval. This achieves stable disabling of the single-channel transmission output, improving the performance and reliability of optical communication equipment under room temperature conditions.

[0091] Step S2023: If the midpoint output power is less than both the upper limit output power and the lower limit output power, then the midpoint voltage of the interval is taken as the next upper limit voltage; or, if the midpoint output power is greater than both the upper limit output power and the lower limit output power, then the midpoint voltage of the interval is taken as the next lower limit voltage.

[0092] In this embodiment, when the midpoint output power is less than the upper and lower limits of output power, the midpoint voltage is used as the next upper limit voltage; conversely, when the midpoint output power is greater than the upper and lower limits, the midpoint voltage is used as the next lower limit voltage. This operation effectively adjusts the search interval, making the search process more intelligent and efficient. By comparing the midpoint output power with the upper and lower limits, the search direction can be clearly defined, gradually approaching the heating adjustment voltage corresponding to the minimum output power. This dynamic adjustment of the search interval fully utilizes the current search results, avoids blind searching, and improves the accuracy and speed of the search. Under normal temperature conditions, this helps to more accurately control the single-channel output power of the silicon photonics module, enabling the single-channel transmission output to be more stably disabled, enhancing the adaptability and robustness of optical communication equipment to different output power conditions, and providing strong support for the stable operation of the optical communication system.

[0093] Step S2024: Return to the step of determining the midpoint voltage of the voltage search interval based on the average value between the upper limit voltage and the lower limit voltage, until the difference between the upper limit voltage and the lower limit voltage matches a preset equivalent threshold, and then use the midpoint voltage of the interval as the heating adjustment voltage.

[0094] In this embodiment, by continuously returning to the step of determining the midpoint voltage of the interval based on the average value between the upper and lower voltage limits, the search process can continue and gradually converge. This iterative approach ensures accurate searching for the heating adjustment voltage corresponding to the minimum output power. The midpoint voltage of the interval is only used as the heating adjustment voltage when the difference between the upper and lower voltage limits matches a preset equivalent threshold, ensuring that the finally determined voltage has sufficient accuracy. Under normal temperature conditions, this step makes the single-channel output power control of the silicon photonics module more accurate and reliable, and can stably disable the single-channel transmit output.

[0095] In a specific embodiment, it is detected whether the difference between the upper limit voltage and the lower limit voltage is within the threshold range corresponding to the preset equivalent threshold. If the difference is within the threshold range corresponding to the preset equivalent threshold, it is determined that the difference between the upper limit voltage and the lower limit voltage matches the preset equivalent threshold. If the difference between the upper limit voltage and the lower limit voltage is not within the threshold range corresponding to the preset equivalent threshold, the step of determining the midpoint voltage of the interval based on the average value between the upper limit voltage and the lower limit voltage is repeated.

[0096] Furthermore, in some feasible embodiments, after step S201: detecting whether the current ambient temperature is within a preset room temperature threshold range, the subsequent silicon photonics module single-channel control method further includes step B10.

[0097] Step B10: After determining that the current ambient temperature is not within the normal temperature threshold range, if the current ambient temperature is greater than the upper limit of the normal temperature threshold range, then the heating adjustment voltage corresponding to the minimum light output power of the heating module at the current ambient temperature is determined according to the high temperature relationship model; or, if the current ambient temperature is less than the lower limit of the normal temperature threshold range, then the heating adjustment voltage corresponding to the minimum light output power of the heating module at the current ambient temperature is determined according to the low temperature relationship model.

[0098] In this embodiment, when the current ambient temperature is determined to be outside the normal temperature threshold range, the heating adjustment voltage corresponding to the minimum output power can be accurately determined by selecting either a high-temperature relationship model or a low-temperature relationship model based on the comparison between the current ambient temperature and either the upper or lower normal temperature threshold. This not only fully considers the characteristic changes of the silicon photonics module under different temperature conditions but also improves the adaptability and stability of the optical communication equipment in disabling single-channel Tx output under various temperature environments. Specifically, for high-temperature situations where the current ambient temperature is higher than the upper normal temperature threshold, adjustments are made according to the high-temperature relationship model to ensure that the single-channel output power is accurately adjusted to the minimum under high-temperature environments, achieving the disabling of single-channel transmission output. Similarly, for low-temperature situations where the current ambient temperature is lower than the lower normal temperature threshold, adjustments are made according to the low-temperature relationship model to ensure reliable system operation under low-temperature environments. This case-by-case processing method enables the optical communication equipment to accurately disable the single-channel Tx output of the silicon photonics module within different temperature ranges.

[0099] Furthermore, in some feasible embodiments, step B10 above: determining the heating adjustment voltage corresponding to the minimum light output power of the heating module at the current ambient temperature based on the high-temperature relationship model, may also include the following implementation steps:

[0100] Step B101: Determine the temperature difference between the current ambient temperature and the normal temperature threshold, and determine the reference high temperature corresponding to the temperature difference.

[0101] Step B102: Superimpose the reference high temperature onto the current ambient temperature to obtain a temperature adjustment value, and determine the heating adjustment voltage output by the heating module corresponding to the minimum light output power based on the high temperature relationship model and the temperature adjustment value. The model algorithm corresponding to the high temperature relationship model is: MPD_out = A*T ad 2 +B*V h 2 +C*T ad *V h +D*T ad +E*V h +F, where MPD_out is the minimum output power, T ad V is the temperature adjustment value. h The heating adjustment voltage is the one corresponding to the minimum output light power. A is the quadratic coefficient of the temperature adjustment value, b is the quadratic coefficient of the heating adjustment voltage, C is the interaction coefficient between the temperature adjustment value and the heating adjustment voltage, D is the linear coefficient of the temperature adjustment value, E is the linear coefficient of the heating adjustment voltage, and F is a preset constant coefficient.

[0102] In this embodiment, by determining the temperature difference between the current ambient temperature and the normal temperature threshold, and further determining the reference high-temperature temperature corresponding to this temperature difference, a quantitative assessment of the degree to which the current temperature deviates from the normal temperature state is achieved. This provides an accurate basis for subsequent temperature adjustments, enabling the system to make targeted adjustments based on the actual temperature deviation. Next, the reference high-temperature temperature is superimposed on the current ambient temperature to obtain the temperature adjustment value. This method cleverly utilizes temperature deviation information to simulate a temperature value closer to the high-temperature state. Based on the high-temperature relationship model and this temperature adjustment value, the heating adjustment voltage corresponding to the minimum light output power of the heating module is determined to ensure that the single-channel TX output can be effectively adjusted to a disabled state under various high-temperature environments.

[0103] Furthermore, in another feasible embodiment, step B10: determining the heating adjustment voltage corresponding to the minimum light output power of the heating module at the current ambient temperature based on the low temperature relationship model may also include the following implementation steps.

[0104] Step C10: Determine the temperature change between the current ambient temperature and the normal temperature threshold. If the temperature change varies by a certain amount (e.g., 5°C), adjust the reference low temperature threshold accordingly (e.g., 1°C). Based on the difference between the current ambient temperature and the adjusted reference low temperature threshold, the actual low temperature can be accurately calculated. Next, based on the low temperature relationship model and the actual low temperature, determine the heating adjustment voltage output by the heating module corresponding to the minimum light output power.

[0105] In this embodiment, real-time monitoring and quantification of temperature changes are achieved by determining the temperature change between the current ambient temperature and the normal temperature threshold. The reference low-temperature threshold is adjusted accordingly whenever the temperature change varies by a certain margin. This dynamic adjustment method allows for more flexible adaptation to different temperature variations, improving the adaptability of the fitted model to temperature fluctuations in low-temperature environments. Next, the actual low-temperature temperature is accurately calculated based on the difference between the current ambient temperature and the adjusted reference low-temperature threshold. Subsequently, based on the low-temperature relationship model and the actual low-temperature temperature, the heating adjustment voltage corresponding to the minimum light output power of the heating module is determined. This enables precise control of the single-channel output power of the silicon photonics module in low-temperature environments, ensuring that the single-channel Tx output can be effectively disabled in low-temperature conditions.

[0106] It should be noted that the algorithm corresponding to the low-temperature relationship model is as follows:

[0107] MPD_OUT=f(T_adjusted, Heater Voltage)

[0108] MPD_OUT is the minimum output power, T_adjusted is the actual low temperature, and Heater Voltage is the heating adjustment voltage corresponding to the minimum output power.

[0109] In summary, this application provides a single-channel control method for silicon photonics modules, enabling the disabling of a single-channel Tx output from the silicon photonics module. Specifically, the single-channel control method described in this application is applied to the control module of an optical communication device. This control module is electrically connected to both a heating module and the silicon photonics module, with the heating module located in the single-channel optical element area of ​​the silicon photonics module. Responding to a single-channel disable command from the silicon photonics module, the control module can quickly and accurately determine the heating adjustment voltage corresponding to the minimum output power based on the current ambient temperature of the single-channel optical element area and a preset fitting model. Subsequently, the heating operating voltage of the heating module is adjusted to the heating adjustment voltage, thereby ensuring that the output power of the single-channel Tx channel in the single-channel optical element area is at its minimum output power. In other words, the optical signal intensity output by the single-channel Tx channel at its minimum output power is very weak, preventing the corresponding single-channel Rx channel in the silicon photonics module from receiving a valid optical signal. Thus, without affecting the other Tx output, the single-channel Tx output is disabled by softly shutting down the optical path involved in the single-channel Tx output.
