Abstract:
An optical switch comprising an array of voltage-controlled interferometric switching elements. Different configurations and modes of operation are possible, but in each configuration the elements are arranged relative to the input and output fibers, such that a beam of light is incident or outgoing at an angle of 45 degrees to the surface of a corresponding element. This permits each element to be electronically controlled to either transmit or reflect light, such that the output beam exits the switch either parallel to or perpendicular to the input beam.
