Abstract
Various 3-port and 4-port micromachined optomechanical matrix switches are disclosed herein. In accordance with one aspect of the invention there is provided an optomechanical matrix switch including a substrate and a first plurality of optomechanical switching cells coupled thereto. Each of the first plurality of optomechanical switching cells is arranged to be in optical alignment with a first input port. A second plurality of optomechanical switching cells is also coupled to the substrate, each of the second plurality of optomechanical switching cells being in optical alignment with a second input port. In another aspect of the present invention an optomechanical matrix switch is provided which includes a substrate and a first plurality of optomechanical switching cells coupled thereto. Each of the first plurality of optomechanical switching cells is placed in optical alignment with one of a corresponding first plurality of input ports and with one of a corresponding first plurality of output ports. The matrix switch further includes a second plurality of optomechanical switching cells coupled to the substrate. Each of the second plurality of optomechanical switching cells is pl…
