摘要 介绍了几种基于相干光的光码分多址(OCDMA)相位编/解码器。分别给出了采用空间光调制器(SLM)、平面光波导(PLC)、超结构光纤布喇格光栅(SSFBG)技术的OCDMA编/解码器的工作原理及最新研究进展,并分析了它们的特点。基于SSFBG的编/解码器在产生超长光学码方面是最好的;平面光波导编/解码器由于可实现单片集成,也是一种很有前途的器件。 The optical code division multiple access （OCDMA） phase encoders/decoders （E/Ds） based on coherent system are introduced. The operation principle and recent progresses are discussed for E/Ds of spatial light modulator （SLM）, planar lightwave circuit （PLC） and superstructure fiber Bragg grating （SSFBG） respec- tively. The characteristics of these E/Ds are analyzed. The E/Ds based on SSFBG are the best devices for the generation of ultra long optical codes. PLC E/Ds are suitable for integration in a chip, so they are perspective as well.
