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 well region in a semiconductor substrate layer. In one embodiment, the well region has a higher doping concentration than the semiconductor substrate layer in which the well region is disposed. The optical switching device is optically coupled to an optical input port and an optical output port of the integrated circuit die.
