Abstract
There is disclosed a micro-mechanical switch mounted on a waveguide structure that can be utilized as a switching device in optical networks. The device comprises an individually deflectable element suspended over a gap in a waveguide. The individually deflectable element has attached to its underside a vertical metal shutter which can be raised or lowered by the movement of the element. The raising or lowering of the shutter is used to control light propagating through the waveguide.
