Abstract

A wavelength demultiplexer (100) includes a beam splitter (105) with an input port (110) receiving a multiplexed signal, and a plurality of output ports for outputting demultiplexed signals. The output ports (120, 140, 160) contain wavelength-selective elements (130, 150, 170), such as tunable band pass filters, and, optionally, shutters. To compensate for the power losses within the demultiplexer, active optical fiber (175) amplifies the multiplexed signal. The demultiplexer may be used in WDM optical transmission systems as a wavelength-selective switch.
