1. An optical device comprising:
an optical switch array comprising:
a plurality of first buses;
a first multiplexer coupled to the first buses and configured to selectively connect one of the first buses to a first voltage, while disconnecting others of the first buses;
a plurality of second buses;
a second multiplexer coupled to the second buses and configured to selectively connect one of the second buses to a second voltage, while disconnecting others of the second buses;
a plurality of optical switches, each optical switch coupled to a first bus and a second bus, each pair of first and second buses coupled to an optical switch; and
a controller for coupling a selected optical switch between the first and second voltages by controlling the first and second multiplexers to selectively connect the first and second buses the selected optical switch is coupled to.
