DETAILED DESCRIPTION

[0017] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the drawings. However, those skilled in the art can understand that in the embodiments of the present application, many technical details are proposed in order to make the readers better understand the present application. However, the technical solutions claimed by the present application can be implemented even without these technical details and various changes and modifications based on the following embodiments. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present application. The embodiments can be combined and referenced with each other on the premise of not contradicting.

[0018] For the convenience of understanding the embodiments of the present application, the related content about electro-optic frequency comb is introduced first.

[0019] Electro-optic frequency comb is a special light source, whose spectrum is composed of a series of equally spaced, high-intensity and coherent frequency components, similar to the shape of the teeth of a comb, hence the name "frequency comb". It realizes the modulation of laser through electro-optic effect, thereby generating such comb-shaped spectrum, and is one of the important branches of optical frequency comb. The flexibility and stability of electro-optic frequency comb make it play an important role in many fields. In the field of microwave photonics, the high frequency stability of optical frequency comb is used to generate microwave signals with ultra-low phase noise, or to realize optical control microwave filter, phase shifter and other devices. With its unique modulation mechanism and performance advantages, electro-optic frequency comb has become a key tool for connecting optical and microwave frequency domains, and promoting the development of precision measurement and optoelectronic technology.

[0020] In the scenarios of dynamic spectrum sensing, high-speed communication and other scenarios that require dynamic regulation of the spectral characteristics of electro-optic frequency comb, the traditional electro-optic frequency comb generation scheme has the following core technical problems: Low tuning efficiency: relying on manual adjustment of radio frequency driving signal parameters, it is difficult to realize the synchronous and collaborative adjustment of multiple device parameters, resulting in long time consumption of electro-optic frequency comb generation and tuning, and difficulty in meeting the real-time requirements of dynamic scenarios.

[0021] Limited precision: manual adjustment of parameters is difficult to accurately match the "target spectrum shape", resulting in insufficient precision of the generated electro-optic frequency comb spectrum characteristics.

[0022] Lack of collaborative control logic: the adjustment of a single device parameter in the traditional scheme may disrupt the balance of other parameters, resulting in poor stability of the spectrum shape and inability to maintain the target performance during dynamic tuning.

[0023] The present application proposes an electro-optic frequency comb dynamic regulation method, which constructs a mapping relationship table of spectrum shape parameters and multiple device control parameters, and realizes the collaborative regulation of multiple devices based on the mapping relationship table, quickly generates or tunes the electro-optic frequency comb that meets the target, avoiding the trial-and-error process of manual parameter-by-parameter adjustment in the traditional method, and breaking through the bottleneck of low efficiency, poor precision and weak adaptability of traditional manual tuning, realizing efficient, accurate and dynamic regulation of electro-optic frequency comb.

[0024] The implementation details of the electro-optic frequency comb dynamic regulation method of the present embodiment will be described in detail below. The following content is only provided for the implementation details for the convenience of understanding, and is not necessary for implementing the present scheme.

[0025] Embodiment one: The electro-optical frequency comb dynamic regulation method of the embodiment can be applied to electronic devices with communication, calculation and data storage capabilities, and the specific process can be as shown in Figure 1 , including: Step 110, obtaining a pre-constructed mapping relationship table, the mapping relationship table being used to represent the corresponding relationship between the spectral shape parameter and the multi-device control parameter set; the multi-device control parameter set being used to control the multi-device to perform the parameter adjustment operation; In this step, the mapping relationship table can be stored in a local computer or a cloud server, and the mapping relationship table used to represent the corresponding relationship between the spectral shape parameter and the multi-device control parameter set can be constructed through a preliminary experiment.

[0026] Specifically, before obtaining the pre-constructed mapping relationship table, it further includes constructing the mapping relationship table. In one embodiment, constructing the mapping relationship table includes: Step 111, initializing the multi-device, the multi-device including: a microwave source, a phase shifter, a modulator, and an electric amplifier; Step 112, setting the spectral shape parameter, determining the effective control parameter of the multi-device that satisfies the corresponding spectral shape of the spectral shape parameter within the control parameter adjustment range of the multi-device; Step 113, obtaining the effective control parameter of the multi-device as the multi-device control parameter set, and establishing the corresponding relationship between the spectral shape parameter and the multi-device control parameter set.

[0027] The process of constructing the mapping relationship table can include hardware preparation, parameter experiment and data arrangement, and finally form the structured storage of the corresponding relationship. Specifically, first, the hardware architecture of the electro-optical frequency comb generation system is built to complete the physical connection of the hardware device; as shown in Figure 2 , the hardware architecture of the electro-optical frequency comb generation system includes optical signal generation and modulation device, electric signal driving device, control device and monitoring device.

[0028] Among them, the optical signal generation and modulation device includes a continuous wave laser, a phase modulator and an intensity modulator. The electric signal driving device includes: a microwave source (microwave signal generator), a power divider, a program-controlled (programmable control) phase shifter, and an electric amplifier; the electric amplifier includes an electric amplifier 1 and an electric amplifier 2. The control device includes a control module and a bias controller; the monitoring device includes a spectrometer.

[0029] Each device is connected according to a pre-set link, as shown in Figure 2As shown, the optical signal output by the continuous wave laser is sequentially connected to the phase modulator, the intensity modulator, and the optical spectrum analyzer; the microwave signal output by the microwave source is divided into two paths by the power divider to provide driving signals, one path is connected to the electrical amplifier 1 and the phase modulator, and the other path is connected to the programmable phase shifter, the electrical amplifier 2, and the intensity modulator. The bias controller is connected to the intensity modulator, and through the preset mapping relationship table, the joint control of the microwave frequency and power, the phase shift of the phase shifter, and the bias control bias value is realized.

[0030] Exemplarily, the continuous wave laser outputs single-frequency continuous light as the seed light source of the optical frequency comb. The phase modulator and the intensity modulator are selected as the electro-optic modulator of lithium niobate crystal, and the working bandwidth covers 0-20GHz. The control module is selected as a processing unit with control function, such as a computer or FPGA, and a preset mapping relationship table is built-in, and the signal output ends thereof are respectively electrically connected to the microwave source, the programmable phase shifter, and the bias controller. The signal generated by the microwave source is a sinusoidal wave radio frequency signal. The phase adjustment accuracy of the programmable phase shifter is 1°, and the working bandwidth covers 8-12GHz; the gain of the electrical amplifier 1 is greater than 24dB; and the gain of the electrical amplifier 2 is greater than 30dB. The bias controller is connected to the direct current bias port of the intensity modulator for adjusting the working point thereof. The optical spectrum analyzer is connected to the output fiber of the intensity modulator for monitoring the spectral characteristics of the optical frequency comb.

[0031] Then, the parameter calibration and initial configuration of each hardware device are performed, such as the parameter calibration and initial configuration of the continuous wave laser, the modulator, the microwave source, and the like, to ensure that each module is in a standard working state. Next, a plurality of preset spectral shapes can be set through parameter optimization and data acquisition, and for each preset spectral shape, the effective control parameters of the plurality of devices under the preset spectral shape are determined within the control parameter adjustment range of the plurality of devices. Specifically, the output frequency and power of the microwave source, the phase shift of the programmable phase shifter, the bias value of the bias controller, and the like can be changed systematically through the experimental system, and the spectral shape parameters of the optical frequency comb of the optical spectrum analyzer, such as the comb tooth spacing and the flatness, are synchronously collected, and the spectral power distribution is analyzed. Exemplarily, a single device parameter, such as the microwave frequency / power, the phase shifter phase shift value, and the bias controller voltage, can be adjusted point by point (repetition frequency / comb tooth spacing), and the spectral characteristics of the optical comb, such as whether the comb tooth spacing meets the target and whether the flatness meets the standard, are synchronously monitored through the optical spectrum analyzer.

[0032] The combination data of the multi-device control parameters and the spectrum shape parameters meeting the preset spectrum shape requirement are screened out. For example, the combination data of the multi-device control parameters meeting the preset spectrum shape requirement is screened out, and the target spectrum shape meeting the preset condition is, for example, flatness ≤ 3 dB at a specific comb spacing. Therefore, the effective control parameter combination can be screened out from the combination data of the multi-device control parameters according to the preset spectrum shape requirement, and the corresponding multi-device control parameter set is, for example, microwave frequency 9 GHz, microwave power 5 dBm, phase shifter phase shift 85°, and bias voltage 1300. The spectrum shape parameters corresponding to the preset spectrum shape meeting the preset condition and the multi-device control parameter set are recorded. Therefore, the corresponding relationship between the spectrum shape parameters meeting the preset spectrum shape and the multi-device control parameter set can be established, and the measurement of the spectrum shape parameters is mainly realized by the spectrum analyzer.

[0033] The spectrum shape parameters include at least one of comb spacing, flatness, comb number, comb power, and spectrum width. The effective control parameters include microwave frequency, microwave power, phase shifter phase shift, modulator bias voltage, and gain of the electric amplifier. The corresponding relationship between the spectrum shape parameters corresponding to each spectrum shape and the multi-device control parameter set is stored in a structured manner to form a mapping relationship table, which provides a retrieval basis for subsequent online regulation. For example, the entries in the mapping relationship table in the above example represent the following meanings: the multi-device control parameter set corresponding to flatness ≤ 3 dB at a specific comb spacing is microwave frequency 9 GHz, microwave power 5 dBm, phase shifter phase shift 85°, and bias voltage 1300.

[0034] In this embodiment, the mapping relationship table constructed is stored in the control module (such as the storage module of PC / FPGA), and the pre-construction process is completed to provide data support for parameter retrieval and collaborative control in subsequent online regulation.

[0035] For example, as shown in Table 1 below: Table 1

[0036] As shown in Table 1, the corresponding relationship between the spectrum shape parameters and the multi-device control parameter set is exemplarily shown. For example, the spectrum shape parameters include spectrum shape parameter 1 and spectrum shape parameter 2. The spectrum shape parameter 1 is exemplarily a comb spacing, and the comb spacing is 8 (GHz) and 9 (GHz). The spectrum shape parameter 2 is exemplarily flatness, and the number of combs with flatness < 3 dB is ≥ 11. The multi-device control parameter set includes device A parameters, device B parameters, and device C parameters. For example, the device A parameters are microwave power / dBm, the device B parameters are phase shifter phase shift / °, and the device C parameters are bias voltage of the bias voltage controller.

[0037] The comb tooth spacing (repetition frequency) refers to the frequency interval between two adjacent comb teeth in the optical comb spectrum, is a basic parameter of the optical comb, and directly determines the frequency distribution density of the optical comb. The flatness is the power uniformity of each comb tooth of the optical comb, and reflects the stability of the spectral power distribution. The number of comb teeth is the total number of effective comb teeth contained in the optical comb spectrum, especially the number of comb teeth meeting the flatness and other characteristic requirements, and is an important parameter for measuring the spectral coverage capability. The comb tooth power is the power level of a single or overall comb tooth, which needs to be ensured within the range allowed by the application scenario to meet the demand for signal strength. The spectral width is the frequency range covered by the optical comb spectrum, i.e., the total span from the lowest frequency comb tooth to the highest frequency comb tooth, which needs to match the requirement of the signal bandwidth of the application scenario. These parameters jointly define the spectral shape of the optical comb, and are also the key basis for judging whether the spectral shape of the optical comb meets the application requirements.

[0038] Step 120, based on the target spectral shape parameters and the mapping relationship table, controlling the multi-device cooperative regulation to output the target spectral shape.

[0039] This step is an online regulation stage. According to the explicit target spectral shape parameters (core parameters), the user can input the requirements through the host computer (such as PC) or the input / output (I / O) module, such as the comb tooth spacing (repetition frequency), such as 8GHz or 9GHz; the flatness, such as the number of comb teeth with flatness <3dB≥11; and other characteristic parameters such as the number of comb teeth and the spectral width according to the application scenario.

[0040] The control module looks up the corresponding multi-device control parameter set in the mapping relationship table according to the target spectral shape parameters input by the user, controls the multi-device cooperative regulation by using the multi-device control parameter set, and finally realizes the output of the optical frequency comb in accordance with the target spectral shape. In this step, the realization of automatic cooperative regulation relies on the accurate mapping of the mapping relationship table and the synchronous regulation of the multi-device, realizing the efficient conversion from the target spectral shape parameters to the actual spectral shape.

[0041] Specifically, based on the target spectral shape parameters and the mapping relationship table, the multi-device cooperative regulation is controlled to output the target spectral shape, including: Step 121, according to the target spectral shape parameters, looking up the corresponding multi-device control parameter set from the mapping relationship table to generate corresponding control instructions.

[0042] Exemplarily, as Figure 3As shown, the control module (such as a PC or FPGA) is built-in with a mapping table, and after the control module receives the target spectral shape parameters through the input unit I / O, it can search for the corresponding multi-device control parameter set in the mapping table through parameter matching algorithms such as index lookup. For example, if the target spectral shape parameters are: comb spacing 9 GHz, comb number 11 with flatness < 3 dB, which represents that the target spectral shape meets the preset condition of comb number 11 with flatness < 3 dB at a specific comb spacing. As shown in Table 1, the control module locates the multi-device control parameter set from the mapping table, such as the microwave frequency and microwave power 5 dBm, the phase shifter phase shift 85°, and the bias voltage controller bias voltage 1300. The control module converts the retrieved multi-device control parameter set into programmable control instructions recognizable by each device, which can be as follows: for the microwave source, set the target frequency and power such as 5 dBm; for the phase shifter, set the target phase shift value such as 85°; for the modulator bias voltage controller, set the target bias voltage such as 1300.

[0043] Step 122, based on the control instructions, control the multi-device control parameter set to perform parameter adjustment operations on the corresponding multiple devices to form the target spectral shape.

[0044] As shown in Figure 2 and Figure 3 , the control module sends the control instructions to the execution devices, which can include a microwave source, a programmable phase shifter, and a bias voltage controller. After receiving the control instructions, the multiple devices synchronously perform parameter adjustment operations based on the control instructions. For example, the microwave source outputs a radio frequency signal with a set frequency and power according to the instructions; the programmable phase shifter adjusts to the target phase shift value to ensure phase matching of the radio frequency signal; and the bias voltage controller adjusts the bias voltage to set the working point of the modulator. In this process, the abstract target spectral shape requirement is converted into executable device operation parameters, and through the one-to-one correspondence between the multi-device control parameter set and the multiple devices, automatic collaborative control is achieved.

[0045] In other embodiments, parameters of a point amplifier can also be included, as shown in Figure 2 , the electrical amplifier amplifies the signal according to the instructions to drive the phase modulator and the intensity modulator. As shown in Figure 2 , the optical signal path is a single-frequency light output by a continuous wave laser, which is cooperatively modulated by the phase modulator and the intensity modulator to generate a comb spectrum that meets the target spectral shape parameters. Through synchronous adjustment of multiple devices, it ensures that the core parameters of the spectral shape, such as comb spacing, are accurate and flatness is stable, thereby avoiding spectral distortion caused by fluctuations in single-device parameters.

[0046] The method for dynamically regulating an electro-optical frequency comb provided in this embodiment can quickly retrieve the corresponding multi-device control parameter set based on the target spectral shape parameter to drive the multi-device to complete the adjustment, thereby avoiding the trial-and-error process of manual parameter-by-parameter adjustment in the traditional method, and breaking through the bottleneck of low efficiency, poor precision, and weak adaptability of traditional manual tuning, and achieving efficient, accurate, and dynamic regulation of the electro-optical frequency comb. Moreover, the method for dynamically regulating an electro-optical frequency comb has universality and reusability. In different application scenarios, only the corresponding target spectral shape parameter, such as different comb tooth spacings and spectral widths, needs to be input, and the same regulation logic can be used to generate an electro-optical frequency comb that meets the requirements, without the need to redesign the regulation architecture, thereby providing reliable technical support for applications with high real-time requirements and variable scenarios.

[0047] Embodiment Two The method for dynamically regulating an electro-optical frequency comb of this embodiment can be applied to electronic devices with communication, computing, and data storage capabilities. Most of the content of the method for dynamically regulating an electro-optical frequency comb of this embodiment is the same as that of the above-mentioned embodiment. The difference between this embodiment and the above-mentioned embodiment is that this embodiment is a further description of step 120 in the above-mentioned embodiment.

[0048] In this embodiment, in the process of controlling the multi-device to cooperatively regulate based on the target spectral shape parameter and the mapping relationship table to output the target spectral shape, the total time consumed for the multi-device to cooperatively regulate based on the target spectral shape parameter and the mapping relationship table is less than a preset time length, and the preset time length is a real-time response threshold of the target application scenario for the output of the target spectral shape. The target application scenario includes real-time spectrum sensing and high-speed communication.

[0049] In this embodiment, some target application scenarios have very short output time requirements for the target spectral shape, and some require the generation / tuning speed of the target spectral shape to be on the order of milliseconds or even nanoseconds, which requires an efficiency improvement of 3-4 orders of magnitude compared to traditional manual tuning to adapt to dynamic scenarios such as real-time spectrum sensing and high-speed communication that require fast response. Therefore, the total time consumed for generating the corresponding control instruction by controlling the multi-device control parameter set to retrieve the corresponding multi-device control parameter set from the mapping relationship table based on the target spectral shape parameter, and controlling the multi-device control parameter set to perform parameter adjustment operations on the corresponding multiple devices based on the control instruction, is less than the preset time length.

[0050] Specifically, in the specific application scenarios of the electro-optical frequency comb, such as real-time spectrum sensing, high-speed communication and the like, in order to ensure the normal implementation of the scene functions, such as real-time tracking of spectrum changes and high-speed signal uninterrupted transmission, the application scenario requires that the tuning response of the electro-optical frequency comb must be completed within a real-time response threshold, which is based on the core requirement of the scene for response speed, or is the maximum allowed time limit of the tuning response of the electro-optical frequency comb required by the application scenario. For example, in the real-time spectrum sensing scene, if the spectrum signal changing at the microsecond level needs to be tracked, the real-time response threshold may be set to the microsecond level; in the high-speed communication scene, in order to match the data frame transmission period, the threshold may be set to the millisecond level, therefore, the total time obtained by adding the time from the generation of the control instruction based on the control module to the sending of the control instruction to the time for the parameter adjustment of each device must be less than the real-time response threshold to meet the scene requirements, which ensures that the tuning method can meet the real-time requirements of the dynamic scene for the rapid generation and tuning of the electro-optical frequency comb, and solves the problem of low efficiency of traditional manual tuning and the inability to adapt to dynamic scenes.
