Abstract
A switch comprises two photoconductive semiconductors and two corresponding laser diodes driven by opposing voltage sources. The two photoconductive semiconductors are connected in series between a high and low voltage source with a radio frequency output at a center node between the photoconductive semiconductors. Each photoconductive semiconductor may include one ohmic contact and one schottky contact for superior bandwidth and efficiency.
