Abstract:
1. An apparatus comprising a wavelength-selective optical switch that comprises: an optical AWG demultiplexer having N optical outputs; a first optical AWG multiplexer having N optical inputs; a second optical AWG multiplexer having N optical inputs; and a plurality of controllable 1×P optical switches, each of the optical switches being connected to a corresponding one of the optical outputs of the optical AWG demultiplexer and being connected to corresponding ones of the optical inputs of the respective first and second optical AWG multiplexers, the P being greater than or equal to 2; and wherein the optical AWG demultiplexer has an optical AWG sampling coefficient of one or more for light with a wavelength in the optical telecommunication C-band, L-band, or S-band.
