Abstract

In this paper, a simple novel all-optical exclusive OR (XOR) logic gate architecture based on Sagnac interferometric loop mirror is proposed for the first time. Using Semiconductor Optical Amplifier (SOA) as nonlinear medium, and through numerical analysis, this scheme is proved to exceed the operation speed limit due to the limited carrier recovery time of the SOA. In order to optimize the operation performance of the proposed XOR logic scheme, the SOA parameters and the signal parameters are discussed. The operation of this scheme with 80Gb/s RZ pseudorandom bit sequences (PRBS) is simulated with fairly high performance.
