Abstract
A demultiplexer (10) for a wavelength-multiplexed optical signal. A series of optical filters (13) along an input line (12) each select a signal component of a given wavelength. An optical shutter (14) receives the output of each filter (13), and is operated so as to either block or pass the filtered signal component. The filters (13) and shutters (14) may be made using integrated circuit fabrication techniques, and the entire demultiplexer (10) may be made as a monolithic device.
