[0002] In the field of optical communication, as the core component of optical module signal transmission, the optical performance stability of a silicon optical chip directly determines the data transmission quality. The OER extinction ratio (Optical Extinction Ratio) is a key indicator for evaluating the performance of the chip, and needs to meet the requirements of the industry's common MSA protocol (Multi-Source Agreement). That is, the OER extinction ratio should not exceed 5.5db when working normally.
[0003] At present, the detection and processing method for the OER extinction ratio of a silicon optical chip in the industry is to collect an optical eye diagram through a DCA device (Digital Communication Analyzer) to realize post-detection. This method cannot capture the abnormal risk of the optical extinction ratio of the silicon optical chip in real time, and often only intervenes after a fault occurs, which easily leads to an increase in the bit error rate of the silicon optical module and signal interruption, and affects the stable operation of high-speed silicon optical products such as 200G and 1.6T. In particular, in the data center scenario, the failure of the silicon optical module will directly cause the interruption of the business link, and the problem of real-time monitoring of the abnormality of the optical extinction ratio of the silicon optical chip needs to be solved.

[0009] The power ratio parameter is compared with a preset ratio range, and when it is detected that the power ratio parameter is not in the preset ratio range, it is determined that the silicon optical chip has an abnormal risk of optical extinction ratio.
[0010] The detection result indicating that the silicon optical chip has an abnormal risk of optical extinction ratio is output.
[0011] In addition, to achieve the above-mentioned purpose, the present application also provides a silicon optical chip monitoring device, which comprises:

Based on the input and output monitoring values, a power ratio parameter is calculated, transforming discrete single-point optical power data into data that reflects the chip's optical power transmission matching characteristics in real time. The quantitative indicators provide core data for anomaly detection that is updated in real time and can be directly compared. By comparing the power ratio parameter with a preset ratio range, when the power ratio parameter is detected to be outside the preset ratio range, it is determined that there is a risk of optical extinction ratio anomaly in the silicon photonics chip. This enables dynamic anomaly identification based on real-time quantitative parameters, without manual intervention. It can locate the risk of optical extinction ratio anomaly as soon as the power ratio deviates from the normal range due to chip aging. The output includes the detection result of the presence of optical extinction ratio anomaly risk, ensuring that maintenance personnel or control systems can obtain risk information as soon as possible, thereby improving the real-time performance of anomaly detection of optical extinction ratio in silicon photonics chips.

The implementations described in the following exemplary embodiments are not meant to represent all implementations consistent with the present application.
[0027] In the field of optical communication, silicon optical chips are the core of optical module signal transmission, and the OER extinction ratio thereof needs to meet the MSA protocol (≤5.5db) to ensure the quality of data transmission. At present, the industry often uses DCA equipment to collect optical eye diagrams to detect the OER extinction ratio. This method is a post-detection method, which cannot capture the OER abnormal risk in real time during the operation of the chip, and often handles the fault after it occurs, which easily leads to the increase of the bit error rate of high-speed silicon optical modules, signal interruption, and even causes the interruption of data center service links, and the problem of real-time monitoring of the abnormality of the optical extinction ratio of the silicon optical chip needs to be solved.
[0028] The present application provides a silicon optical chip monitoring method, device, electronic equipment and computer readable storage medium, which realizes real-time detection of the abnormality of the optical extinction ratio of the silicon optical chip.
[0029] It should be noted that the execution subject of the present embodiment can be a computing service device with data processing, network communication and program running functions, such as a device capable of realizing the above functions, such as an electronic device. The present embodiment and the following embodiments will be described below taking an electronic device as an example.
[0030] The silicon optical chip monitoring method of the present application comprises the following implementation steps S10 to S40.
[0031] Step S10: obtaining input monitoring values and output monitoring values integrated by the silicon optical chip itself, wherein the input monitoring values are input optical power values collected by input monitoring photodiodes integrated by the silicon optical chip itself, and the output monitoring values are output optical power values collected by output monitoring photodiodes integrated by the silicon optical chip itself;
[0032] As an example, the silicon optical chip monitoring method of the present application can be applied to high-speed optical communication transmission scenarios or high-density data interaction scenarios, such as real-time performance monitoring of 200G / 1.6T / 3.2T silicon optical modules, and is suitable for application scenarios with high requirements for the optical extinction ratio stability of silicon optical chips, such as data center internal interconnection, long-distance trunk communication, enterprise-level core network, etc., to ensure that the OER abnormal risk caused by chip aging is identified in time, and to ensure the quality of optical signal transmission and system operation reliability.
[0033] Optionally, the silicon optical PIC (Photonic Integrated Circuit, optical integrated circuit, i.e. silicon optical chip), MPD In (Monitoring Photodiode Input, input monitoring photodiode, integrated in the silicon optical PIC, used to collect the input optical power of the chip), MPD Out (Monitoring Photodiode Output, output monitoring photodiode, integrated in the silicon optical PIC, used to collect the output optical power of the chip), OER (Optical Extinction Ratio, optical extinction ratio, a key indicator for evaluating the performance of the silicon optical chip, which needs to meet the requirements of the MSA protocol (Multi-Source Agreement, multi-source agreement), and the normal working time is usually not more than 5.5db), DCA device (Digital Communication Analyzer, digital communication analyzer, a device in the prior art for offline collection of optical eye diagram to detect OER).
[0034] Optionally, the optical eye diagram of the test TX silicon optical OER extinction ratio shows that when the DCA test OER extinction ratio is about 4db, the performance of the silicon optical chip is good; when the OER extinction ratio exceeds the MSA protocol requirement of 5.5db or even reaches 7db, it indicates that the silicon optical chip has signs of aging.
[0035] Optionally, as shown in Figure 2 , Figure 2 is a schematic diagram of the optical power values of the MPD input and output of the silicon optical chip involved in the present application. The transmission and monitoring architecture of the optical power values of the MPD input and output of the silicon optical chip itself is suitable for high-speed optical communication scenarios. In the system, a single-mode wavelength 1310-1550nm DFB laser is used as a light source, which is transmitted to an isolator through a lens, and then input into the silicon optical chip. The output end of the silicon optical chip is sequentially output through a lens and an FA (fiber amplifier), and then output through an MPO optical port. At the same time, the silicon optical chip integrates MPD In (input monitoring photodiode) and MPD Out (output monitoring photodiode): MPD In collects the input optical power of the chip, and MPD Out monitors the output 2dbm optical power (including the 2dBm power of the silicon optical chip). The data of the two is connected to the MCUAD acquisition module to realize real-time acquisition of optical power and subsequent ratio value calculation, to provide a data basis for abnormal risk monitoring of OER caused by aging of the silicon optical chip, and to support performance monitoring of 200G / 1.6T silicon optical modules.
[0036] Optionally, the embodiment is applied to a high-speed silicon optical module running scenario, and the silicon optical chip itself integrates an input monitoring photodiode (MPD In) and an output monitoring photodiode (MPD Out), wherein the MPD In is used to collect an input optical power value at the input end of the chip, and the MPD Out is used to collect an output optical power value at the output end of the chip.
[0037] Optionally, in this scenario, the prior art needs to collect an optical eye diagram detection optical extinction ratio (OER) offline through a DCA device, and the embodiment directly obtains the input optical power value collected by the MPD In and the output optical power value collected by the MPD Out integrated in the silicon optical chip itself; a power ratio parameter is calculated based on these optical power values, and the parameter includes but is not limited to a ratio of the output optical power value to the input optical power value; the parameter is compared with a preset ratio range, if the parameter is not in the range, it is determined that the chip has an OER abnormal risk; and a detection result containing the risk is output.
[0038] Optionally, the MPD Out can monitor the silicon optical chip output 2dbm optical power in real time, and the MPD In synchronously collects the chip input end optical power data to provide accurate original parameters for ratio value calculation.
[0039] The embodiment has the beneficial effect that the chip optical power data can be obtained in real time without relying on external devices, real-time monitoring of OER abnormalities is realized, and the problem of fault expansion caused by post-detection in the prior art is avoided.
[0040] Optionally, on the basis described above, the input monitoring point and the output monitoring point integrated in the silicon optical chip itself are determined, real-time data collection is performed thereon, collected data of at least two input monitoring points are randomly selected as input optical power values, and collected data of corresponding output monitoring points are selected as output optical power values; a mapping corresponding relationship of the input and output optical power values is established to obtain at least two groups of monitoring value corresponding groups; a chip model parameter is obtained, a matching target ratio calculation algorithm is determined through a preset mapping relationship of the model parameter and the ratio calculation algorithm (including but not limited to a corresponding table of the model and the ratio formula), and the algorithm operation is performed on each monitoring value corresponding group to obtain a power ratio parameter.
[0041] The embodiment has the beneficial effect that the accuracy of the power ratio parameter is improved through the multiple monitoring value and model matching algorithm, and the monitoring needs of different models of silicon optical chips are adapted.
[0042] Step S20: a power ratio parameter is calculated according to the input monitoring value and the output monitoring value;
[0043] Optionally, the prior art needs to collect the optical eye diagram detection OER through the DCA device offline, and the embodiment directly obtains the input optical power value (such as a monitoring value of 0.4 dbm) collected by the MPD In integrated in the silicon optical PIC and the output optical power value (such as a monitoring value of 2 dbm) collected by the MPD Out; the collection data of at least two input monitoring points are randomly selected as the input optical power value, and the collection data of the corresponding output monitoring point are selected as the output optical power value; a mapping corresponding relationship of the input and output optical power values is established, and at least two groups of monitoring value corresponding groups are obtained; the model parameters of the silicon optical PIC are obtained, a mapping relationship (including but not limited to a corresponding table of a 200G model corresponding to an "output optical power value / input optical power value" and a 1.6T model corresponding to a special ratio formula) of the preset model parameters and the ratio calculation algorithm is determined, a matched target ratio calculation algorithm is determined, the algorithm operation is performed on each group of monitoring value corresponding groups, and a power ratio parameter (an initial calibration power ratio of a certain model is 0.4, and a normal range includes but is not limited to 0.2-0.6, the range is an example, and different models of different manufacturers can be 0.27 or 0.4-0.8, etc.).
[0044] Optionally, on the basis of the above, the initial calibration power ratio value (factory calibration standard power ratio value) corresponding to the silicon optical PIC model parameter is obtained, and a preset variation threshold (such as 50%, when the variation is greater than the threshold, the silicon optical PIC has an aging failure risk); taking the initial calibration power ratio value as a reference, the variation threshold is floated up and down to form a preset ratio range (such as an initial calibration ratio of 0.4, a threshold of 0.2, and a range of 0.2-0.6, when the power ratio parameter is less than 0.2, it is determined to be abnormal); the actual variation (the absolute value of the difference between the two, such as the current ratio of 0.2, the variation is 0.2) of the power ratio parameter and the initial calibration power ratio value is calculated; if the power ratio parameter exceeds the preset range or the actual variation is greater than the threshold, it is determined that the silicon optical PIC has an OER abnormal risk (such as OER=7.0db); the risk determination conclusion, the power ratio parameter, the actual variation and the model parameter are integrated into the initial detection result, which is classified and labeled according to the preset information labeling rule and the risk level (high / low) is determined, and the result is output through real-time visual display, local data storage or transmission to external control equipment (including but not limited to the three ways); the current optical power values of MPD In and MPD Out are re-collected, the target ratio parameter is calculated by the target ratio calculation algorithm, and the current power ratio parameter of the silicon optical PIC is adjusted to the target value (such as OER=4.5db after adjustment, such as the bit error rate is reduced, such as the CH4 channel bit error rate is reduced from 1.26E-07 to 1.88E-11) by a software algorithm at one time; based on the OER abnormal risk level, it is judged whether the silicon optical PIC after adjustment meets the preset optical performance standard (including OER threshold, bit error rate threshold, different rate products have different test conditions, such as single wave 100G supports 0-70℃, single wave 200G does not support 0℃, transmission distance includes 500 meters, 2km, 10km, etc.), if not, re-collect, the number of times is not more than 3.
[0045] Optionally, as shown in Figure 3 Figure 3 A schematic diagram of the change curve of the maximum optical power point when the ratio value involved in the present application remains unchanged, wherein the horizontal axis X is the optical power distribution interval, and the vertical axis Y is the optical power intensity; two curves are included, corresponding to the optical power distribution states before and after the aging of the silicon optical chip respectively: the curve before aging has a higher peak value, representing that the maximum optical power point is at a more optimal level; the curve after aging has a lower peak value and a morphological shift, indicating that the silicon optical chip has performance degradation due to aging, even if the ratio value does not change, the actual output maximum optical power will still decrease; specifically, the aging of the silicon optical chip will cause the internal optical transmission characteristics to deteriorate, even if the power ratio parameter (ratio) is maintained within the initial range, the absolute value distribution of the optical power will also abnormally shift, ultimately affecting the transmission quality of the optical signal, and even causing OER extinction ratio abnormalities, indicating the hidden risks of silicon optical chip aging, and also verifying that relying only on the ratio value to determine the performance has limitations, and comprehensive monitoring needs to be combined with the actual distribution state of the optical power.
[0046] The embodiment does not need to rely on peripheral devices such as DCA, but uses the MPD In and MPD Out integrated in the silicon optical PIC to collect optical power data in real time, and realizes real-time monitoring and parameter calibration of OER abnormalities caused by silicon optical PIC aging through a model matching algorithm and dynamic adjustment logic, which adapts to the monitoring needs of silicon optical chips of different manufacturers and different rates, avoids the problems of module bit error rate increase, signal interruption and data center service link interruption caused by after-detection of the prior art, and directly causes OER extinction ratio abnormalities when the ratio value changes too much. The embodiment can effectively prevent the ratio value change caused by silicon optical chip aging, and thus avoid the problem of OER extinction ratio abnormalities.
[0047] Step S30: comparing the power ratio parameter with the preset ratio range, and determining that the silicon optical chip has an optical extinction ratio abnormal risk when it is detected that the power ratio parameter is not in the preset ratio range;
[0048] Optionally, the initial calibration power ratio (the standard power ratio calibrated by the silicon optical PIC when it leaves the factory), the change threshold (the maximum amplitude of the deviation of the power ratio from the initial calibration value, such as 50%), the preset ratio range (an interval formed by the initial calibration ratio and the upper and lower floating change threshold, such as 0.2-0.6 when the initial 0.4 and the threshold 0.2), and the actual change amount (the absolute value of the difference between the power ratio parameter and the initial calibration ratio).
[0049] Optionally, the input optical power value collected by the MPD In integrated in the silicon optical PIC and the output optical power value collected by the MPD Out are obtained; at least two input monitoring point data are randomly selected as the input optical power value, and corresponding output monitoring point data are selected as the output optical power value; a mapping corresponding relationship between the two is established to obtain at least two groups of monitoring value corresponding groups; the model parameters of the silicon optical PIC are obtained, and a matching target ratio calculation algorithm is determined through a preset mapping relationship between the model parameters and the ratio calculation algorithm (including but not limited to a corresponding table of the model and the ratio formula); the algorithm operation is performed on each monitoring value corresponding group to obtain the power ratio parameter.
[0050] In another embodiment, on the basis of the above, the initial calibration power ratio corresponding to the model of the silicon optical PIC (such as 0.4) and the preset variation threshold (such as 50%) are obtained; the initial calibration ratio is taken as a reference, and the variation threshold is floated up and down to form a preset ratio range (such as 0.2-0.6); the actual variation of the power ratio parameter and the initial calibration ratio (such as the variation is 0.2 when the current ratio is 0.2) is calculated; if the power ratio parameter is out of the preset range or the actual variation is greater than the threshold, it is determined that the silicon optical PIC has an abnormal risk of OER (such as OER=7.0db); the risk judgment conclusion, the power ratio parameter, the actual variation and the model parameter are integrated into an initial detection result, which is classified and labeled according to a preset information labeling rule and a risk level is determined, and the result is displayed in real time, stored locally or transmitted to an external control device; the current optical power values of the MPD In and the MPD Out are re-collected, the target ratio parameter is calculated using the target ratio calculation algorithm, and the current power ratio parameter of the silicon optical PIC is adjusted to a target value (such as the adjusted OER=4.5db is normal, and the bit error rate is reduced) by a software algorithm at one time; whether the silicon optical PIC after adjustment meets the preset standard of optical performance is judged based on the abnormal risk level of OER, and if not, the collection is re-collected, and the number of times is not more than 3.
[0051] In this embodiment, the optical power data is collected in real time by the MPD In and the MPD Out integrated in the silicon optical PIC, and the OER abnormality caused by the aging of the silicon optical PIC is identified in real time through the model matching algorithm and the dynamic threshold comparison, which is suitable for silicon optical chips of different manufacturers and different rates, and avoids the module failure and service interruption caused by the post-detection of the prior art.
[0052] Step S40: outputting a detection result indicating that the silicon optical chip has an abnormal risk of optical extinction ratio;
[0053] Optionally, the optical extinction ratio abnormal risk (such as the risk of the silicon optical chip exceeding the MSA protocol ≤5.5db standard due to aging), the initial detection result (such as the integrated risk judgment conclusion, the power ratio parameter, the actual change amount, and the basic information set of the model parameter), the preset information labeling rule (including but not limited to the rule of labeling according to "product identification-detection data-risk level"), and the preset output mode (including but not limited to real-time visual display, local data storage, and transmission to external control equipment).
[0054] Optionally, the input optical power value collected by the MPD In integrated in the silicon optical chip and the output optical power value collected by the MPD Out are obtained, the power ratio parameter is calculated, the parameter is compared with the preset ratio range, and if it is not in the range, it is determined that the chip has an optical extinction ratio abnormal risk; the risk judgment conclusion, the power ratio parameter, the actual change amount, and the chip model parameter are integrated into the initial detection result; the initial detection result is labeled according to the preset information labeling rule, the risk level is determined and labeled synchronously, and the labeled detection result is obtained; and the detection result is output through the preset output mode.
[0055] Optionally, the initial detection result includes the conclusion that a certain model chip "has an optical extinction ratio abnormal risk", the power ratio parameter 0.7, the actual change amount 0.3, and the model parameter 200G; according to the preset information labeling rule, the model parameter is labeled as "product identification: 200G silicon optical module", the power ratio parameter and the actual change amount are labeled as "detection data: ratio=0.7, change amount=0.3", and the risk level is labeled as "high risk"; the result is output through real-time visual display, and the current optical power values of MPDIn and MPDOut are re-collected, the target ratio parameter is calculated using the target ratio calculation algorithm, the chip power ratio parameter is adjusted by software algorithm at one time, it is judged whether the adjusted chip meets the optical performance preset standard, and if not, it is re-collected, and the number of times is not more than 3.

[0057] The embodiment realizes real-time collection of optical power data from the chip end without relying on external detection instruments, and guarantees the real-time basis of abnormal detection from the data collection source, by acquiring input monitoring values and output monitoring values integrated by the silicon optical chip, wherein the input monitoring values are input optical power values collected by an input monitoring photodiode integrated by the silicon optical chip, and the output monitoring values are output optical power values collected by an output monitoring photodiode integrated by the silicon optical chip; the power ratio parameter is calculated according to the input monitoring values and the output monitoring values, the discrete single-point optical power data is converted into a quantitative index that can reflect the chip optical power transmission matching characteristics in real time, and the real-time updated and directly comparable core data basis is provided for abnormal judgment; the power ratio parameter is compared with the preset ratio range, when it is detected that the power ratio parameter is not in the preset ratio range, it is determined that the silicon optical chip has an optical extinction ratio abnormal risk, the dynamic abnormal recognition based on the real-time quantitative parameter is realized, manual intervention is not needed, and the optical extinction ratio abnormal risk can be located at the first time when the chip aging causes the power ratio to deviate from the normal range; and the detection result containing the optical extinction ratio abnormal risk is output, so that the maintenance personnel or the control system can obtain the risk information at the first time, and the real-time abnormal detection of the optical extinction ratio of the silicon optical chip is realized.
[0058] Further, based on the above content, the second embodiment of the silicon optical chip monitoring method is proposed. In some feasible embodiments, the system includes a target detection model, and the step S10 includes the following implementation steps B201-B202.
