Abstract
An optical switch is disclosed which is electrically activatable through received photon energy. The switch may include a substrate responsive to photon energy that forms an optical excitation signal. First and second electrodes may be disposed on first and second surfaces of the substrate. The substrate may have a characteristic of two-photon absorption to enable electrical conduction through the substrate, the two-photon absorption being enhanced by deep energy levels located in a bandgap between conductance and valence bands of the substrate, which are at least near resonant with the photon energy.
