发明名称 Optical switch incorporating therein shallow arch leaf springs
摘要 An optical switch selectively transmits an optical signal to one of multiple optical paths for use in an optical communication. The optical switch includes a mobile structure provided with a mirror surface at one end surface of the mobile structure to change the optical path by moving the mobile structure backward and forward along an axis parallel to the mirror surface. It has at least a pair of leaf springs in the form of a shallow arch, wherein each of the leaf springs is connected to both side surfaces of the mobile structure in a leaf spring axis perpendicular to the mirror surface, respectively, thereby obtaining a latch-up function and an actuator for moving the mobile structure. In the optical switch, elastic bodies are introduced into connection portions of the leaf springs, respectively, to give rise to a degree of freedom to the connection portions in the direction of the leaf spring axis. The elastic body can be an I-shape beam, a multiple spring with a curvature and an S-shape beam allowing angle deflection.
