Paper Abstract

Coherent, passive, linear optical signal processing networks, built with 2 by 2 couplers, gratings, mirrors and waveguides are discussed. The signal processing function is accomplished by the interference of coherent signals. Through the artifice of a generalized coupler complex network topologies are reduced to cascaded four-port and feedback-assisted cascaded four-port circuits, which are then treated by standard network analysis techniques. A wide range of configurations can thus be evaluated through a single numerical code. Several applications relevant to telecommunication, measurement and sensing are enumerated.
