A novel architecture of an optical cross-connect based on tuneable fibre bragg gratings and optical circulators

Abstract

Optical networks have evolved to sustain the growing need for bandwidth in communication networks. Wavelength switched networks using Dense WavelengthDivision Multiplexing (DWDM), are a solution to this problem. Development of these networks demands the use of Optical Cross-connects (OXCs), optical devices that are able to control the communications channels and route them correctly. In this paper, a novel switching architecture based on thermally tuneable Fibre Bragg Gratings (FBG) and optical circulators (OC) is demonstrated.
