OPTICAL SWITCH

摘要

An optical switch performs switching between transmission and total-reflection of incoming light (101) applied to an electro-optical crystal (104), by applying electric field to the electro-optical crystal (104) and changing the refractive index of the electro-optical crystal (104). The optical switch is provided with a plurality of electrodes (105) arranged inside the electro-optical crystal (104) to configure an electrode section (106) for applying electric field to the electro-optical crystal (104). The refractive index changing section (not shown in the figure) wherein the refractive index changes when electric field is applied by the electrode section (106) in the electro-optical crystal (104) includes the entire electrode section (106). The interface of the refractive index changing section is formed flat.
