ABSTRACT:
An optical multiplexer/demultiplexer having a body made up of a pair of reflective and a pair of non-reflective sides. As a demultiplexer a beam containing a plurality of optical wavelengths is separated within the body into its constituent wavelengths utilizing the principles of optical refraction and optical reflection. By extending the length of the body, sufficient physical separation can be realized between each of the constituent wavelengths to allow detection of each wavelength by spacially separated detectors. As a multiplexer a plurality of beams, each having a single wavelength, are combined to provide a single output beam having a plurality of wavelengths contained therein.
