摘要
介绍了光延迟线编/解码器,给出了两种光延迟线变址方案并分析了它们的性能。提出了三种新的编/解码器设计方案:基于步进啁啾FBG(光纤布喇格光栅)的光谱编码器、二维光延迟线编/解码器和多FBG编/解码器。
The encoder/decoder based on optical fiber delay lines (OFDLs) are introduced. Two schemes of tunable OFDLs are presented and their performance is analysed. Three new design schemes for encoder/decoder are put forward: spectral encoder based on stepchirped fiber Bragg gratings (FBGs), twodimensional encoder/decoder based on OFDLs and encoder/decoder based on multiple FBGs.
