摘要： A fast injection optical switch is disclosed. The optical switch includes a thyristor having a plurality of layers including an outer doped layer and a switching layer. An area of the thyristor is configured to receive a light beam to be directed through at least one of the plurality of layers and exit the thyristor at a predetermined angle. At least two electrodes are coupled to the thyristor and configured to enable a voltage to be applied to facilitate carriers from the outer doped layer to be directed to the switching layer. Sufficient carriers can be directed to the switching layer to provide a change in refractive index of the switching layer to redirect at least a portion of the light beam to exit the thyristor at a deflection angle different from the predetermined angle.
