Paper Abstract

We report the performance of an InP-based integrated spectrometer and consider its application in wavelength division multiplexed (WDM) systems. The wavelength multiplexer/demultiplexer operates in the 1.5 micrometers fiber band and disperses 1 nm spaced signals over a spectral range of 75 nm. Crosstalk between the channels is -19 dB and the optical performance of the spectrometer is essentially insensitive to the polarization of the incident light. Use of the device in multiwavelength telecommunication and computer local area networks is discussed.
