[0025] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0026] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below for illustration.

[0027] The path-based optical simulation device activation method provided by the embodiment of the present invention can be applied in the design process of photonic integrated chips. The above process will continuously call the behavior model of each device in the integrated photonic system for simulation and calculation. The traditional simulation method has a large amount of calculation and is time-consuming.

[0028] Figure 1 FIG. 1 is a schematic diagram showing the implementation flow of the path-based optical simulation device activation method provided by an embodiment of the present invention. Figure 1 In this embodiment, the path-based optical simulation device activation method may include steps S101 to S104.

[0029] S101: Acquire a system topology relationship of an integrated photonic system and an internal port relationship of a candidate device, wherein the candidate device is a device in the integrated photonic system, and the internal port relationship is an optical signal transmission relationship between ports in the candidate device.

[0030] In some embodiments, since users frequently change the types, positions and connection relationships of devices during the design of photonic integrated chips, it is necessary to obtain the devices and their connection relationships included in the current integrated photonic system before activating the devices for simulation each time.

[0031] Specifically, the above system topology relationship and internal port relationship are both connection relationships and on-off relationships, which are binary functions and do not involve specific numerical changes of signals during transmission.

[0032] Optionally, the integrated photonic system is a system composed of existing optical devices on the user interface.

[0033] S102: Acquire an input device from the candidate devices, and determine a first port corresponding to the input device according to the system topology relationship and the internal port relationship, where the first port is a port capable of receiving an optical signal sent by the input device.

[0034] Figure 2 FIG. 1 is a schematic diagram showing an application of a path-based optical simulation device activation method provided by an embodiment of the present invention. Figure 2 In a specific example, the integrated photonic system includes at least one input device, namely, a light source. According to the system topology relationship of interconnection between various devices and the internal port relationship of various devices, a port capable of receiving the optical signal emitted by the light source is determined as the first port A.

[0035] In some embodiments, obtaining the input device from the candidate devices in S102 may include:

[0036] Obtain a system input port of the integrated photonic system.

[0037] An alternative device including the system input port is used as the input device.

[0038] S103: Acquire an output device from the candidate devices, and determine a second port corresponding to the output device according to the system topology relationship and the internal port relationship, where the second port is a port capable of transmitting an optical signal to the output device.

[0039] See also Figure 2 In a specific example, the integrated photonic system includes at least one output device, namely, a detector. According to the system topology relationship of interconnection between the various devices and the internal port relationship of the various devices, a port capable of transmitting an optical signal to the output device is determined as the second port B.

[0040] In some embodiments, obtaining the output device from the candidate devices in S103 may include:

[0041] A system output port of the integrated photonic system is obtained.

[0042] An alternative device including an output port of the system is used as the output device.

[0043] S104: Determine an activated device among the candidate devices according to the first port and the second port.

[0044] In some embodiments, the specific implementation of S104 may include:

[0045] A third port is acquired, where the third port is a port that is both the first port and the second port.

[0046] The candidate device including the third port is used as the activated device.

[0047] See also Figure 2 In a specific example, device 1, device 3, and device 4 including the third port are used as activated devices, and other devices do not need to be activated during this simulation process.

[0048] The path-based optical simulation device activation apparatus provided in this embodiment can easily and quickly determine the devices that need to be activated in the integrated photonic system, thereby effectively simplifying the simulation process and reducing the amount of calculation.

[0049] In some embodiments, after S104, the path-based optical simulation device activation method may further include:

[0050] A behavioral model of the activation device is invoked.

[0053] A third port in the activation device and an initial behavior model of the activation device are obtained.

[0054] A portion of the initial behavior model related to the third port is selected as the behavior model of the activation device.

[0055] Figure 3 Another application schematic diagram of the path-based optical simulation device activation method is shown. Figure 3 The device shown is an activated device, wherein port 1, port 6, port 7 and port 8 are first ports A; port 2, port 3, port 4 and port 5 are second ports B. Then only port 1 and port 5 are both first port A and second port B, that is, port 1 and port 5 are third ports. In the initial behavior model of the device, the portion between port 1 and port 5 is selected as the behavior model of the activated device.

[0056] In some embodiments, the initial behavior model includes an S matrix and the behavior model includes a simplified S matrix.

[0057] In a specific example, for an eight-port activation device, the S matrix of its initial behavior model can be:

[0058]

[0059] When port 1 and port 5 are the third ports, their behavior model is s 51 It can be seen that using behavioral models to simplify the simulation of integrated photonic systems can greatly reduce the amount of calculation and time in the simulation process and improve the simulation computing power.
