Paper Abstract

In this communication we present all-optical AND, NOT XOR and NOR gates with two and three input logic signals using the cross-polarization modulation (XPolM) effect in a semiconductor optical amplifier (SOA). The gates utilize only a SOA and they need neither an inversion stage nor an additional synchronized clock. The XpolM effect is discussed as well as its repercussion on the polarization-state of a probe beam crossing a SOA perturbed by the power of a control beam. Based on this discussion, we present the design criteria allowing the implementation of the all-optical logic gates with two and three input logic signals. Finally the gates are experimentally demonstrated with input logic signals modulated with a 2.5 Gb/s NRZ code with a pseudo-random data sequence of 223-1 length.
