OPTICAL DEVICE AND SUBSTRATE

摘要

An optical device of photonic crystal structure for constituting an optical integrated circuit readily comprising a first electrode, an electro-optical substrate provided on one surface of the first electrode and made of a solid material, a photonic crystal structure region provided in the electro-optical substrate and made of a solid material, a second electrode provided in the photonic crystal region and formed in a pattern on the surface opposed to the one surface, a means for applying a voltage between the first and second electrodes, means for directing a light beam to the photonic crystal region under the second electrode, and means for receiving the light beam guided by the photonic crystal structure region under the second electrode.
