Abstract
A switching device includes an insulated gate bipolar transistor (IGBT) or MOSFET having a gate, an emitter, and a collector configured to allow current to pass between the emitter and the collector based on voltage applied to the gate. A stack of alternating layers of photo-sensitive p-n junction layers and insulating layers stacked on the gate for optical switching control of voltage through the IGBT or MOSFET.
