Description

technical field [0001] The invention relates to the technical field of photonic integrated devices, in particular to a silicon-based optical transceiver component for parallel optical transmission. Background technique [0002] Since the beginning of the new century, with the continuous development of micro-nano optoelectronic integration technology, the integration level of chips has become higher and higher, the size of optoelectronic devices has been continuously reduced, and the operating speed has been continuously increased. In order to increase the optical communication capacity, parallel optical fibers are used to realize one-to-one communication of multi-channel lasers / detectors, such as the PSM4 scheme (Parallel Single Mode 4, parallel single-mode scheme) to achieve high-density optical transmission. [0003] At present, most of the solutions to realize parallel optical fiber transmission are realized based on array VCSEL (surface emitting laser), array PD (detecto...

AI Technical Summary

Problems solved by technology

The optical transmission scheme based on VCSEL has the disadvantage of short transmission distance, while the parallel optical transmission scheme based on edge-emitting lasers (such as DFB, FP, etc.) has a coupling tolerance when coupled with the array single-mode fiber due to the small spot size of the laser Small, low-yield problems
