Abstract

We propose a novel DWDM over OCDMA scheme with parallelly combined Super-Structured Fiber Bragg Grating (SSFBG) based encoder/decoders. In our scheme, a group of SSFBGs with the same code but different central reflection frequencies are parallelly combined together to support larger number of DWDM channels. The number of DWDM channels per code can be increased without increasing the chip-rate of SSFBG. The performance of a 27-channel (9-DWDM × 3-OCDMA) system is investigated by simulation, and error-free transmission is achieved for all 27 channels.
