An integrated wavelength demultiplexer and PIN detector array is reported for high density WDM detection at 1.5 mu m. Signals spaced at 1 nm over the 1.48-1.55 mu m wavelength range are separated and detected; channel passbands are 0.6-0.8 nm. Grown on a semi-insulating substrate, and providing a pseudoplanar device surface, the HD-WDM detector array is suitable for monolithic integration with high-speed multichannel receiver circuitry.
