Multiplexers and Demultiplexers Based on Fibre Bragg Gratings and Optical Circulators for DWDM Systems

摘要

Two different architectures of multiplexers/demultiplexers based on 4 * 1 and 1 * 4 configurations are discussed. These architectures are implemented using apodized fibre Bragg gratings as optical filters and optical circulators. The spectral characteristics of the devices for channel separations of 100 GHz and 50 GHz are analysed and their performance is evaluated. Optical switch and cross-connect configurations are also demonstrated.
