Photonic switch for dense wavelength division multiplexed (DWDM) network; directs wavelength from associated egress area along set output path, and combining it into output multi-channel signal transmitted on port

摘要

A switch (2) may direct a wavelength along an optical path from an assigned ingress area to an associated egress area selected from a number of egress areas. An optical multiplexer (50) such as optical grating directs a wavelength from an associated egress area along a set output path, and combining it into an output multi-channel signal transmitted on an output port. An Independent claim is included for: (a) a method of routing a wavelength within a photonic switch
