Planar grating wavelength demultiplexer


A reflection grating wavelength demultiplexer fabricated on planar silica-on-silicon is investigated for use both as a multi-channel demultiplexer and as part of a fast single-wavelength selector device. Design and characterization of a preliminary grating device which resolves 128 channels with 0.85 nm channel spacing are presented in this paper.
