ABSTRACT:
An optical switch matrix is described herein. In one embodiment, an exemplary optical switch matrix includes, but is not limited to, multiple input waveguides, multiple output waveguides, for each of the input waveguides and each of the output waveguides, a switching node coupling the respective input waveguide and the respective output waveguide. The switching node includes a first switch coupling the respective input waveguide to an intermediate waveguide and a second switch coupling the intermediate waveguide to the respective output waveguide. The second switch is an X switch having first and second input ports and first and second output ports, the first input port receiving the intermediate waveguide and the first output port coupling to the respective output waveguide. Other methods and apparatuses are also described.
