Abstract
A planar lightwave circuit design for implementing complementary spectral keying encoders and decoders is presented. The design uses only one arrayed-waveguide grating integrated with arrays of thermo-optic phase shifters and attenuators in a reflective structure. The result is a compact, low component count, programmable spectral keying switch that can implement a variety of spectral encoding/decoding functions.Keywords
