PURPOSE:To provide the optical switch for fetching an arbitrary one in an optical fiber group, and outputting it to an arbitrary one in the optical fiber group by controlling a movement of a slide table 5. CONSTITUTION:First optical fiber groups 1a-1c are arrayed at an equal interval on a slide table 5, and first lens groups 2a-2c convert light of first optical fiber groups 1a-1c to parallel rays. Second lens groups 3a-3d are arrayed at an interval being different from that of first lens groups 2a-2c on a fixed base 6, and condense the parallel rays from first lens groups 3a-3d. By moving the slide table 5, one light in first optical fiber groups 1a-1c is outputted to one in second optical fiber groups 4a-4d. |
