1. A method of operating a wide bandgap optical device, comprising:
illuminating the wide bandgap optical device with a light within a first range of wavelengths and a first average intensity, thereby allowing a current to propagate therethrough without substantial absorption of the current;
illuminating the wide bandgap optical device with light within the first range of wavelengths and a second average intensity that is lower than the first average intensity to allow a sustained current flow though the wide bandgap optical device; and
illuminating the wide bandgap optical device with light within a second range of wavelengths to stop or substantially restrict propagation of the current through the wide gap material.
