ABSTRACT:
This invention is an optical Multiplexer/Demultiplexer, built from a plurality of optical waveguides. Each waveguide differs in length from its neighboring waveguide by a predetermined amount. The waveguides are strongly coupled to one another at their respective ends, and substantially uncoupled therebetween, allowing for high efficiency.
