Optical grating based multi-input demultiplexer for multiple sets of interleaved wavelength channels

摘要

An optical device for demultiplexing a plurality of interleaved sets of wavelength channels is described. The device supports at least two input ports in which each input port receives a plurality of optical channels corresponding to the normal output of an optical frequency interleaver. These signals are separated by the device in dependence of wavelength. This device, being bidirectional will also operate as a multiplexer.
