Technology Description:

The University of Buffalo is developing an optically controlled high voltage power switching device for enhanced resiliency, reliability, and control of power flow in grid applications. The proposed switches would be made of the ultrawide-bandgap material beta-gallium oxide, which offers benefits including high breakdown strength, scalable melt-grown substrates, and ease of material processing. The University of Buffalo would use an optical cascode architecture to achieve high slew rate operation and noise immunity for the devices.
