Optical switch
Abstract:
An optical switch changes the refractive index of an electro-optical crystal according to an electric field applied to the electro-optical crystal so as to switch depending on whether the electro-optical crystal enables incident light to pass through or whether the electro-optical crystal enables incident light to be totally reflected. The optical switch includes an electrode section including a plurality of electrodes and formed in the electro-optical crystal, a principal plane including the largest area of each electrode on a same plane of the electro-optical crystal; an insulator layer on at least one plane of the electro-optical crystal, the plane being parallel with the electrode section, the insulator layer made of an insulator with lower dielectric constant than the electro-optical crystal; and a temperature control device formed on and in contact with the insulator layer and controls a temperature of the electrode section or dissipates heat generated in the electrode section.
