Apparatus and method for high speed optical signal processing

摘要

In one aspect of the invention, an apparatus operable to facilitate optical signal processing includes a micro-electro-optic system (MEMS) device having a moveable mirror layer operable to receive a first copy of an input signal from a beam splitter and to reflect the first copy of the input signal for combination with a second copy of the input signal at an output to form an output signal. The moveable mirror layer being displaceable in a substantially piston-like motion to introduce a phase shift between the first and second signal copies at the output. The amplitude of the output signal varying depending on the displacement of the moveable mirror layer.
