Abstract: A wavelength demultiplexer having at least two photodetectors is disclosed. The photodetectors are arranged in sequential layers along an optical path. The photodetectors differ in bandgap, and are arranged so that the optical signal passes through relatively larger bandgap photodetectors before being received by relatively smaller bandgap detectors. Each photodetector absorbs photons within a predetermined energy range and generates a voltage as a function of the absorbed energy. The photodetectors can be used to detect, and hence demultiplex, a wavelength-division-multiplexed signal.

Abstract: In accordance with the invention, a WDM optical communication system includes a new tunable multi-channel dispersion compensating filter (13) having low loss, low polarization dependence and capable of compensating many channels over a large wavelength range. In essence, the filter comprises an optical cavity (27) with a near 100% reflector (29) on one side and a variable partial reflector (19) on the other side. The device acts as a tunable all-pass filter.
