Title: Programmable multiplexer/demultiplexer
Inventor: MAROM DAN MARK
IPC: H04B10/00
Filed: 2002-06-18
Abstract: PROBLEM TO BE SOLVED: To provide programmable optical multiplexer/demultiplexer. SOLUTION: The programmable optical demultiplexer independently allocates all input optical channels in a WDM optical communication signal and outputs them from a desired output port. The demultiplexer can be operated in an opposite direction. Thus, different wavelengths can be received in multiple input ports and the multilevel wavelength channels are combined in the multiple output ports. Consequently, the programmable optical multiplexer is realized. The programmable multiplexer/demultiplexer have optical constitutions which spatially disperse the optical wavelengths, and they independently give directions to the respective channels by using a tunable micro mirror. Thus, connection between the input port and the output port is decided in a wavelength level by controlling the reflecting direction of a beam.
