Abstract
This invention relates to demultiplexing, routing and multiplexing of a number of different optical wavelength channels. The demultiplexer provides a basis for robust designs of multi-channel optical communication receiver, spectrum analyzer and router. The demultiplexer is operationally bi-directional providing a means for multiplexing.
