Abstract: This paper reports our research on bipolar optical correlator using four wave mixing (FWM) effect. With analytical reduce and numerical calculation, after analysis on the multiple access interference(MAI) and other noises including amplified spontaneous emission(ASE), shot noise, receiver noise, and etc., signal to noise ratio and bit error rate are given as the evaluation of the system performance.

Key words: optical code division multiple access, four wave mixing, optical correlator
