摘 要: 本文提出了一种在步进啁啾光纤光栅实现OCDMA频阈相位编码的方案 ,该方案中引入了影射码 ,根据影射码在相应的子光栅之间加入相移以实现正确的编解码 该编解码器结构简单 。 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.
