Abstract
A multiplexer/demultiplexer having a holographically formed reflective grating incorporated therein. In operation as a demultiplexer a single signal having a plurality of wavelengths impinges upon the holographic reflective grating in an appropriate manner and is separated into a plurality of signals, each being of a different one of the wavelengths. In the multiplexing mode of operation, a plurality of signals, each being of a different wavelength impinges upon the holographic reflective grating in an appropriate manner and emerges therefrom as a single signal having all of the different wavelengths.
