Abstract

A coding/decoding setup for a spectral phase encoding optical code-division multiple access (SPE-OCDMA) system has been developed. The proposal is based on the temporal self-imaging effect and the use of an easily tunable electro-optic phase modulator to achieve line-by-line coding of the transmitted signal, thus assuring compatibility with WDM techniques. Modulation of the code is performed at the same rate as the data, avoiding the use of high-bandwidth electro-optic modulators. As proof of concept of the technique, experimental results are presented for a back-to-back coder/decoder setup transmitting a 10GHz unmodulated optical pulse train within an 80GHz optical window and using 8-chip Hadamard codes.

OCDMA network scheme for the proposed setup with K users. The upper branch of user I (green) corresponds to the transmitter and the lower branch (red) to the receiver. Code J is used at the transmitter to communicate with user J, while code I * is used at the receiver to decode the information (MLL, mode-locked laser; PC, polarization controller; LC-FBG, linearly chirped fiber Bragg grating).
