ABSTRACT:
A multiplexer/demultiplexer having a series of novel interferometer elements optically aligned with one another in a stacked relationship. Each of the interferometer elements being made up of a plurality of reflective elements forming an optical path therebetween and a pair of beamsplitters for directing a beam of radiant energy into or out of the optical path. The optical path of each interferometer element being defined for resonance at a different frequency whereby in operation as a multiplexer a plurality of beams of radiant energy, each of a predetermined frequency, emerge from the multiplexer/demultiplexer as a single beam of radiant energy having a multitude of frequencies or in operation as a demultiplexer a single beam of radiant energy having a multitude of frequencies emerges from the multiplexer/demultiplexer as a plurality of beams radiant energy, each at a preselected frequency.
