Optical Transceiver Microsystem Based on Digital Prototyping and Optoelectronic Collaborative Simulation

In order to meet the urgent demand for high‐speed and high‐capacity data transmission in machine learning, large‐scale simulation, high‐performance computing, etc., we design and demonstrate an optical transceiver microsystem based on digital prototyping and optoelectronic collaborative simulation. Firstly, based on its architecture and fabrication process, we constructed a parameterized model of the optical transceiver microsystem, which is the digital prototype. The digital prototype is composed of the laser model, modulator model, photodetector model, modulator‐driver model, transimpedance‐amplifier model, and power‐supply model. All the device models are precise and have been revised by measured data. Using this digital prototype, we simulated the signal‐transmission characteristics and bit error rate (BER) of the optical transceiver microsystem. Through the digital verification of the digital prototype, high‐cost experiments and fabrication processes can be avoided. Besides, defects in the design scheme can be found early and optimized, thereby guiding the development of the actual optical transceiver microsystems. In order to verify the effectiveness of the digital prototype, we carried out fabrication and optoelectronic integrated packaging of the optical transceiver microsystem. Besides, performance tests were conducted on the developed optical transceiver microsystem. The measured maximum data transmission rate is 25 Gbps, with a BER of 5.56 × 10 −5 . By comparing simulation and measured data, it can be seen that the simulation results of the digital prototype are relatively close to the test results of the physical prototype, which proves the accuracy of the developed digital prototype. The digital prototype development offers great engineering reference value for the agile development of optical transceiver microsystems.
