Description

【Technical field】 [0001] The invention relates to optical transmission and optical conversion technology, in particular to optical coding and optical decoding technology. 【Background technique】 [0002] With the rapid increase of the amount of social information, the information infrastructure is required to have high bandwidth and high speed. The information network must evolve from the traditional circuit switching to overcome the electronic bottleneck and evolve into an all-optical network for transmission and switching in the optical domain. In the optical domain, the optical encoding and optical decoding are performed on the optical signal, the optical encoder implements optical encoding, and the optical decoder implements optical decoding. It is applied in the field of optical communication and all-optical network. The principle is that after the optical signal enters the optical encoder, it is coded and converted according to the preset parameters; and the optical cod...

AI Technical Summary

Problems solved by technology

The basic components of optical communication such as encoders should be applied to large-scale integrated optical circuits. In the application of small batch equipment, the parameters of the PLC are scattered and cannot be adjusted. If the encoder needs to change the parameters slightly, the above encoder cannot meet the requirements.

[0003] The optical encoder with a single technical parameter is difficult to adapt to the flexible matching and adjustment of large-scale planar optical path PLC
