Abstract
A channelized Wavelength Division Multiplex (WDM) equalizer enables the gain of each WDM channel to be individually controlled, enabling power adjustments of each channel over the equalizer's entire dynamic range. The gain equalizer includes a demultiplexer with each of its outputs interfaced to a different microelectromechanical system (MEMS) reflective device which adjusts optical power in response to a received control signal. The equalizer can be implemented to operate in a reflective mode or in a transmission mode.
