Spectral Phase Optical CDMA Coding Based on Step Chirped Fiber Bragg Gratings
基于步进啁啾光纤光栅的OCDMA频阈相位编码

A new method for realizing spectral phase optical CDMA coding based on step chirped fiber Bragg Gratings (SCFBGs) is proposed. In this method, a mapping code is introduced and designed phase shift is inserted to the corresponding subgrating of SCFBG according to the mapping code. The structure of encoder/decoder is simple and good correlation property can be readily obtained as demonstrated by numerical simulation results.
