Abstract
Various embodiments of the present invention are directed to photonic crystal switches. In one embodiment, a photonic crystal switch a photonic crystal switch includes a photonic-crystal-based light transmission layer that outputs an incident light beam in a selected, output direction. The photonic crystal switch may include two or more electrical contacts, positioned relative to the light transmission layer, to which a voltage is applied to select the output direction of the light beam.
