The optical directional coupler, analogous to the microwave element1 of the same name, consists of parallel channel optical waveguides sufficiently closely spaced that energy is transferred from one to
Directional couplers are two waveguides with a small gap between them that “couple,” or transfer, light from one waveguide to another. The term “coupling” comes from multiple eigenmodes of a
