Abstract

Semiconductor optical amplifier (SOA) is among one of the most promising candidate for all optical computation and communication technology implementation. An all optical multiplexer and demultiplexer utilizing SOA-based dual pump four-wave mixing is proposed and explained. A multiplexer and demultiplexer are very important device for both optical computation and communication system and find variety of applications. In this communication, a multiplexer and a demultiplexer are proposed using frequency encoded format. Two very simple but interesting applications of demultiplexer one as decoder of two-bit frequency encoded numbers and another as comparator of frequency encoded single-bit numbers are presented for the first time in this communication. The devices proposed here can show ultra fast speed of operation and compact with advantages of using frequency-encoding technique for representing states of information.
