Analysis and Simulation of All-Optical Router for TDM-Based Optical Networks Using: NOLM

Abstract

The work in this paper addresses all-optical routers for TDM optical networks. The core ofthe optical routers is the demultiplexer. In this paper all-optical router is analyzed andsimulated. It is based on a TDM demultiplexer employing Nonlinear Optical Loop Mirror(NOLM). Expressions are derived for the transmission and reflection coefficients for the loopmirror employed in the demultiplexer. The effect of various system impairments, on theperformance of the demultiplexer, such normal mode loss, control power, and losses, areaddressed in details. Simulation results were carried out using MATLAB 6.5 software. Theresults indicate clearly that the demultiplexer should be designed precisely to achieve therequired router performance.
