摘要：

We have proposed a user extensible optical CDMA system which employs a repeated use of codes in the encoders and the decoders. In this study, we report the user-extension effect by using an array of superstructured fiber Bragg grating (SSFBG) as an encoder and a decoder through the simulations and the experiments. We performed the experiments by using 4 SSFBGs in each encoder and decoder. We have shown that the capable number of users can be increased up to C-63(1).C-63(1).P-63(2) when 63 orthogonal codes are used. (C) 2008 Elsevier Inc. All rights reserved.
