発明の名称 (英語) OPTICAL SWITCH ELEMENT AND OPTICAL SWITCH
発明の概要(英語) An optical switch element SW includes: an optical fiber sensor which has optical fibers (20a, 20b) and a sensor unit SP connected to the optical fibers (20a, 20b) and leaks a part of transmitted light at the boundary between the optical fibers (20a, 20b) so that light is incident at an incident end and light which has passed through the sensor unit SP is emitted at an emission end; and a switching member which operates in a single direction to define a shape of the optical fiber sensor so as to change a curvature of a curve drawn by the optical fiber sensor from curvature R1 to curvature R2 upon one switching between ON/OFF states of the switch and then back to curvature R1. Thus, it is possible to prevent that the sate of the optical fiber sensor having a large curvature continues for a long time.
