[0001] This application relates to the field of communication technologies, and in particular, to a method and apparatus for controlling a laser, an optical module, and a computer device. Background Art

[0002] In the field of communication technologies, a laser can be applied to an optical module. After converting an electrical signal into an optical signal through the laser, the signal can be transmitted through an optical fiber, enabling long-distance transmission of signal data and thus improving the efficiency and quality of communication. However, how to efficiently control the luminous intensity of the laser to achieve signal transmission has become a technical problem that urgently needs to be solved.

[0003] In a possible implementation, a laser control instruction can be transmitted to the laser through a serial communication bus (e.g., Inter-Integrated Circuit bus I2C) to control the laser. However, this method of transmitting the laser control instruction through the serial communication bus takes a long time and cannot meet the hardware timing requirements.

[0004] To meet the hardware timing requirements, general-purpose input / output pins are usually added to the laser to control the turn-on and turn-off of the laser through these pins. This implementation restricts the selection range of the laser, thereby limiting the application scenarios and scope of application of the laser. Summary of the Invention

[0063] Through the above - mentioned drawings, the clear embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0064] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present application. On the contrary, they are merely examples of the devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0065] In this text, the term "and / or" merely describes an associated relationship, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the term "at least one" in this text means any one of multiple items or any combination of at least two of multiple items. For example, including at least one of A, B, and C can represent including any one or more elements selected from the set composed of A, B, and C.

[0066] First, some terms involved in the embodiments of this application are explained.

[0067] I2C: The full English name is Inter-Integrated Circuit, which is an integrated circuit bus and a serial communication bus.

[0068] SPI: The full English name is Serial Peripheral interface, which is a synchronous serial external interface.

[0069] UART: The full English name is Universal Asynchronous Receiver / Transmitter, which is a universal serial data bus.

[0070] IDAC: The full English name is Current Digital-to-Analog Converter, which is an electronic component that converts digital signals into analog current signals.

[0071] It should be noted here that the laser control method provided by the embodiments of this application can be used to control a single laser or the lasers integrated in other modules (such as the lasers integrated in an optical module). The following takes the laser integrated in an optical module as an example for illustration. Among them, the optical module can be a firmware of a single-mode optical module with a transmission rate above 40G for long-distance transmission. For example, the transmission rate of the optical module can be 40G, 100G, or 400G, etc. At this time, the optical module can be applied to at least the following scenarios: 40G / 100GLR4 / ER4 / ZR4, 400G FR4 / DR4 / ER4 / LR4, etc.

[0072] Currently, the control of the laser can be achieved through a serial communication protocol or through general-purpose input / output pins. For example, turning on the laser, turning off the laser, controlling the luminous intensity of the laser, etc.

[0073] Exemplarily, refer to Figure 1 , Figure 1A schematic diagram of an application scenario for controlling a laser in the prior art provided by an embodiment of the present application. As Figure 1 shown, this scenario includes at least a single-chip microcomputer and a laser array. Among them, the laser array includes at least one laser.

[0074] If the control of the laser is achieved through a serial communication protocol, then, Figure 1 the scenario shown may also include a first interface installed at the single-chip microcomputer end and a second interface installed at the laser array end. At this time, the control signal for the laser can be transmitted to the second interface through the first interface according to a matching serial communication protocol (for example, I2C communication protocol, SPI communication protocol, UART communication protocol, etc.), so as to achieve the control of the laser (see Figure 1 the solid line shown). This way of signal transmission through a serial communication interface takes a long time and cannot meet the hardware timing requirements of the laser.

[0075] If the control of the laser is achieved through general-purpose input / output pins, then, Figure 1 the scenario shown may also include the general-purpose input / output pins set at the single-chip microcomputer end and the general-purpose input / output pins set at the laser array end. At this time, the control signal for the laser can be transmitted to the general-purpose input / output pins set at the laser array end through the general-purpose input / output pins set at the single-chip microcomputer end, so as to achieve the control of the laser (see Figure 1 the dotted line shown). This implementation requires general-purpose input / output pins to be set at both the single-chip microcomputer end and the laser array end, which limits the selection range of the laser, thereby limiting the application scenario and scope of application of the laser.

[0076] The control method of the laser provided by the present application aims to combine the control method of the laser with the interrupt service of the single-chip microcomputer by utilizing the characteristic that the interrupt service of the single-chip microcomputer must be executed, so as to solve the above technical problems in the prior art.

[0077] The following will detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems with specific embodiments. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0078] See Figure 2 , Figure 2 is a flowchart of the control method of the laser provided by an embodiment of the present application Figure 1 , as Figure 2 shown, this method includes:

[0079] S201. In response to the received laser control instruction, save each laser control instruction to the execution queue of the interrupt service.

[0080] Among them, the laser control instruction is used to indicate the control of the light intensity of the laser. At this time, the laser control instruction can at least include: laser number information and light intensity information. At this time, according to the laser control instruction, the light intensity of the laser corresponding to the laser number information can be controlled to correspond to the light intensity information. For example, the laser control instruction can indicate: control the light intensity of laser 1 to be 4. At this time, the laser control instruction can be saved to the execution queue of the interrupt service, so that when the interrupt service is executed, the laser control instruction is executed.

[0081] In one example, the laser control instruction can be used to control the light intensity of a single laser or multiple lasers. For example, the laser control instruction can also indicate: control the light intensities of laser 1, laser 2, laser 3, and laser 4 to be 4, etc. At the same time, when the laser control instruction is used to control the light intensities of multiple lasers, the light intensities of the multiple lasers can be controlled to be the same or different, and no specific limitation is made here.

[0082] In one example, the laser control instruction can be initiated by the main program of the single-chip microcomputer or by a network device communicatively connected to the single-chip microcomputer. There is no limitation on the device that initiates the laser control instruction here, and it is subject to actual needs.

[0083] In one example, the number of received laser control instructions can be one or multiple. At this time, when the number of received laser control instructions is multiple, each laser control execution can be saved to the execution queue of the interrupt service according to the initiation order of each laser control instruction, so that when the interrupt service is executed, each laser control instruction is executed in sequence, thereby ensuring that the laser control instruction initiated first can be executed preferentially, and further ensuring the accuracy of the light-emitting state of the laser.

[0084] At this time, the execution queue includes the laser control instructions that have not been executed by the interrupt service, so that the interrupt server can perform control processing on the laser based on each laser control instruction included in the execution queue.

[0085] S202. Execute the interrupt service, and write the target data matching each laser control instruction into the target register in sequence according to the instruction initiation order of each laser control instruction.

[0086] In one example, the target data matching the laser control instruction is used to indicate the light intensity information. For example, the target data can be 0, 1, 2, 4, etc. Here, the value of the target data is not limited and is subject to the specific laser control instruction.

[0087] In one example, the target register is used to indicate the current digital-to-analog converter register. At this time, the received target data can be converted into an analog current signal through the target register, so as to control the light-emitting state of the laser. For example, the target register can be the IDAC register integrated in the single-chip microcomputer.

[0088] S203. Control the light-emitting state of the laser based on the target data sequentially stored in the target register.

[0089] Among them, the light-emitting state of the laser indicates the light intensity of the laser.

[0090] In one example, after converting the stored target data into an analog current signal based on the target register, the analog current signal can be sent to the laser, so as to drive the laser to emit light / turn off, and then realize the control of the laser.

[0091] From the above description, it can be seen that in the embodiment of the present application, after receiving the laser control instruction, in response to the received laser control instruction, each laser control instruction can be saved to the execution queue of the interrupt service, so that in the case of receiving multiple laser control instructions, based on the execution queue of the interrupt service, the execution order of each laser control instruction can be ensured, and the phenomenon of chaotic execution can be avoided, so as to ensure the accuracy of laser light emission. Then, the interrupt service can be executed, so that the single-chip microcomputer can execute the laser control instruction based on the interrupt service, that is, execute the interrupt service, and sequentially write the target data matching each laser control instruction into the target register according to the instruction initiation order of each laser control instruction, so as to control the light-emitting state of the laser based on the target data sequentially stored in the target register. This implementation method can combine the characteristics that the interrupt service in the single-chip microcomputer must be executed and the method of directly controlling the laser through the target register, which can not only meet the hardware timing requirements of the laser, but also realize the rapid control of the laser, thereby improving the control efficiency of the optical module including the laser and further improving the communication efficiency. At the same time, this implementation method also avoids controlling the laser through additional pins or interfaces, which not only saves hardware costs, but also broadens the application scenarios and scope of application of the laser.

[0092] See Figure 3 , Figure 3 is the flow schematic diagram of the laser control method provided by the embodiment of the present application Figure 2, such as Figure 3 shown, the method includes:

[0093] S301. Receive the main program of the single-chip microcomputer and / or the laser control instruction initiated by the network device.

[0094] In one example, the main program of the single-chip microcomputer indicates the firmware main program of the single-chip microcomputer. For example, when the firmware of the single-chip microcomputer detects that the temperature of the laser is too high, a laser control instruction can be initiated to turn off the laser.

[0095] In one example, the network device can indicate the device using the laser in the optical module. Here, the type of the network device is not limited and is subject to being able to achieve the function.

[0096] At this time, the network device can initiate a laser control instruction and transmit it to the single-chip microcomputer to control the light-emitting state of the laser through the single-chip microcomputer, so as to perform signal transmission. Among them, the communication method between the network device and the single-chip microcomputer includes but is not limited to the general-purpose input / output pin communication method. Here, the communication method between the network device and the single-chip microcomputer is not limited.

[0097] S302. Determine the interrupt service for executing the laser control instruction and set the execution priority of the interrupt service to the target priority.

[0098] In one example, the target priority indicates the lowest interrupt priority to avoid interrupting other interrupt services. For example, this interrupt service can be the PendSV (Pended System Service Call) service.

[0099] S303. In response to the received laser control instruction, save each laser control instruction to the execution queue of the interrupt service.

[0100] Among them, the laser control instruction is used to indicate the light intensity of the laser; the execution queue includes the laser control instructions that the interrupt service has not executed.

[0101] In one example, this step can refer to the content described in S201 above and will not be elaborated here.

[0102] S304. Execute the interrupt service and write the target data matching each laser control instruction into the target register in the order of the instruction initiation sequence of each laser control instruction.

[0103] During specific implementation, after executing the interrupt service and before writing the target data into the register, the control mode matching the laser control instruction can be determined based on the value of the target data. Herein, the control mode indicates the mode for controlling the laser to turn on or off. For example, if the value of the target data is the target value, it is determined that the control mode matching the laser control instruction indicates the mode for controlling the laser to turn off; if the value of the target data is not the target value, it is determined that the control mode matching the laser control instruction indicates the mode for controlling the laser to turn on. Herein, the target value can indicate that the light intensity corresponding to the laser is 0, so that the laser is in the off state. At this time, the target value can be 0.

[0104] Then, based on the control mode, the writing method of the target data is determined. Herein, the writing method indicates the stepped writing method or the direct writing method. The step value corresponding to the stepped writing method can be 1, or 2, or 3, etc. Here, the size of the step value is not limited.

[0105] Finally, according to the writing method of the target data, the target data matching each laser control instruction is sequentially written into the target register.

[0106] In an example, if the control mode indicates the mode for controlling the laser to turn on; then, the writing method of the target data determined based on this control mode is the stepped writing method. At this time, if, according to the writing method of the target data, the target data matching each laser control instruction is written into the target register, the cache value in the target register can be determined; in the case where the cache value in the target register is not equal to the value of the target data, the target data is written into the target register according to the stepped writing method. In the case where the cache value in the target register is equal to the target data, the process of writing the target data into the target register is omitted.

[0107] Exemplarily, refer to Figure 4 , Figure 4 which is a schematic flow chart for writing target data into a target register according to the stepped writing method provided by an embodiment of the present application. As Figure 4 shown, when it is determined to write the target data into the target register according to the stepped writing method, the cache value in the target register can be first determined, and then it is judged whether the value of the target data is equal to the cache value in the target register.

[0108] If the value of the target data is equal to the cache value in the target register, the target data of this time is not written, that is, the writing is directly ended. If the value of the target data is not equal to the cache value in the target register, the steps described below can be executed in a loop.

[0109] It is possible to first determine whether the value of the target data is less than the cached value in the target register.

[0110] If so, first determine whether the difference between the value of the target data and the cached value is less than the step value (i.e., Figure 4 the difference between the two shown is less than the step value). If so, the target data can be directly written into the target register, that is, the cached value = the target value. At this time, the cached value in the target register is updated to the target data; if not, the cached value in the target register can be updated based on the step value, that is, the cached value = the cached value - the step value. At this time, the cached value in the target register is updated to the cached value - the step value.

[0111] If not, first determine whether the difference between the value of the target data and the cached value is less than the step value. If so, the target data can be directly written into the target register, that is, the cached value = the target value. At this time, the cached value in the target register is updated to the target data; if not, the cached value in the target register can be updated based on the step value, that is, the cached value = the cached value + the step value. At this time, the cached value in the target register is updated to the cached value + the step value.

[0112] This implementation method can avoid the phenomenon of overcharging of the optical power of the laser.

[0113] In one example, if the control mode indicates a mode for controlling the laser to turn off; then, the writing method of the target data determined based on this control mode is the direct writing method. At this time, the target data can be directly written into the target register. For example, when the cached value in the target register is 5 and the value of the target data is 0, the value in the target register can be directly updated to 0, thereby accelerating the speed of turning off the laser and improving the efficiency.

[0114] Or, when the control mode indicates a mode for controlling the laser to turn off, the determined writing method of the target data can also be the step-by-step writing method to write the target data into the target register in the step-by-step writing method, so as to gradually reduce the light intensity of the laser until it turns off, avoiding the situation of sudden change in the light intensity of the laser.

[0115] S305. Control the light-emitting state of the laser based on the target data sequentially stored in the target register.

[0116] Among them, the light-emitting state of the laser indicates the light intensity of the laser.

[0117] In one example, the content described in the above S203 can be referred to for this step, and details will not be repeated here.

[0118] See Figure 5 , Figure 5Flow schematic of the laser control method provided by the embodiments of the present application Figure 3 , such as Figure 5 shown, the method includes:

[0119] S501. In response to the received laser control instruction, save each laser control instruction to the execution queue of the interrupt service.

[0120] Among them, the laser control instruction is used to indicate the brightness intensity of controlling the laser; the execution queue includes the laser control instructions not executed by the interrupt service.

[0121] S502. Determine whether the laser control instruction controls a single laser.

[0122] If so, execute the steps described in S503 below; if not, execute the steps described in S504 below.

[0123] S503. Execute the interrupt service, and in the order of the instruction initiation of each laser control instruction, sequentially write the target data matching each laser control instruction into the target register.

[0124] S504. Execute the interrupt service, and in the order of the instruction initiation of each laser control instruction, write the target data matching each laser control instruction into the target register corresponding to each laser.

[0125] In an example, see Figure 6 , Figure 6 is a schematic diagram of the application scenario where the laser control instruction provided by the embodiments of the present application is used to control multiple lasers. As Figure 6 shown, this scenario may include a single-chip microcomputer, a network device, and a laser array. As Figure 6 shown, the laser array may include 4 lasers. At this time, the single-chip microcomputer may also include 4 target registers, and each target register can correspond to a laser to control the light-emitting state of the corresponding laser.

[0126] At this time, the laser control instruction initiated by the single-chip microcomputer and / or the network device can be received, and each laser control instruction is saved to the execution queue of the interrupt service. Then, the interrupt service can be executed to sequentially write the target data matching each laser control instruction into the target register corresponding to each laser in the order of the instruction initiation of each laser control instruction. Then, based on the target data sequentially saved in the target register, the light-emitting state of the laser is controlled.
