Ultra-Fast All-Optical Logic XOR Using SOA-MZI with Differential Modulation Scheme

摘要

In this paper, the all-optical logic exclusive OR using integrated SOA-based Mach-Zehnder interferometer with differential modulation scheme is proved to exceed the operation speed limit of the logic XOR with original modulation effectively through numerical analysis for the first time. The SOA Parameters, the signal parameters and the time delay are discussed and designed to optimize the switching performance of the proposed logic XOR. The operation of the proposed logic XOR with 80Gb/s RZ pseudorandom bit sequences is simulated with fairly high performance.
