Abstract
A device for switching an optical beam in an optical switch. In one embodiment, the disclosed optical switch includes an optical switching device disposed in a semiconductor substrate. The optical switch also includes a first optical path through the semiconductor substrate such that the first optical path includes the optical switching device. A second optical path through the semiconductor substrate is included such that the second optical path not including the optical switching device. A first optical confinement layer is disposed between the first and second optical paths.
