Patent ID: 6882771

Claim:
An optical system, comprising: a wavelength division demultiplexer operable to separate a multiple wavelength signal into a plurality of wavelength signals; a first beam splitter operable to receive at least one of the plurality of wavelength signals as an optical input signal, and to communicate at least a first part of the optical input signal in a first path and a second part of the optical input signal in a second path, wherein the first part and the second part of the optical input signal comprise unequal amplitudes; a micro-electro-optic system (MEMS) device comprising a moveable mirror operable to receive the first part of the optical input signal from the first beam splitter and to reflect the first part to an output port to form an output signal, the amplitude of the output signal capable of being varied depending on the displacement of the moveable mirror; and a wavelength division multiplexer operable to receive a plurality of output signal wavelengths and to multiplex at least some of the output signal wavelengths into an optical output signal.
