Wavelength division multiplexed (WDM) systems have several channels of different wavelengths in the 1550 nm wavelength band. Implementation of WDM systems requires demultiplexers to separate the different wavelengths. Compact, low loss demultiplexers can be realized using integrated optical spectrometers. Integrated optical spectrometers may also be used for compact, portable, low cost test instruments that are intended for use on WDM systems. Implementation of WDM systems requires demultiplexers (and multiplexers) to separate the different wavelengths.
