Jb. Soole et al., INTEGRATED GRATING DEMULTIPLEXER AND PIN ARRAY FOR HIGH-DENSITY WAVELENGTH DIVISION MULTIPLEXED DETECTION AT 1.5 MU, Electronics Letters, 29(6), 1993, pp. 558-560
An integrated wavelength demultiplexer and pin detector array is repor
ted for high density WDM detection at 1.5 mum. Signals spaced at 1 nm
over the 1.48-1-55 mum wavelength range are separated and detected; ch
annel 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 r
eceiver circuitry.
