Abstract:
A wavelength division multiplex (WDM) signal equalizer comprisinga WDM signal guided-wave demultiplexer apparatus for receiving an input WDM optical signal and demultiplexing it into a plurality of optical signal channels for output at different output ports of the demultiplexer apparatus, a plurality of independently controllable microelectromechanical system (MEMS) devices, each MEMS device aligned with a different optical channel output port of the demultiplexer apparatus for adjustably controlling a signal level coupled from that optical channel output port of the WDM multiplexer apparatus to an optical apparatus in response to a control signal to that MEMS device, and wherein said WDM demultiplexer apparatus includes a WDM demultiplexer and a plurality of optical fibers having a first end connected to the outputs of the WDM demultiplexer and a second end forming the output ports of the WDM apparatus.
