OPTICAL SWITCH

摘要

Optical fibers (30a-30d) are arranged in parallel. When a movable mirror (26) is outside a space (37), a light from an inputting optical fiber (30a) is bent in direction by a lens (33a), then reflected by a fixed mirror (25), condensed by a lens (33b), and coupled with an outputting optical fiber (33c). When a movable mirror (26) is inside a space (37), a light from an inputting optical fiber (30a) is bent in direction by a lens (33a), then reflected by a fixed mirror (25), further reflected by the fixed mirror (25), reflected by the fixed mirror (25) again, condensed by a lens (33a), and coupled with an outputting optical fiber (33b).
