Abstract
We report an integrated wavelength demultiplexing grating spectrometer and p-i-n array for use in dense wavelength division multiplexing (WDM) applications. The single InP chip incorporates a novel waveguide/detector coupling scheme and is capable of demultiplexing up to 92 wavelength channels. Operation in the 1.5 micrometers fiber band was successfully demonstrated with a channel spacing of 1 nm. The detectors exhibited bandwidths of 15 GHz.
