Abstract
The invention relates to an optical switch which is used for connecting or switching light (optical signals) by utilizing optical fibers. An optical fiber tape (6) is fixed on an optical fiber placing base (2) by an adhesive agent. A plurality of slave side optical fibers (3) are caused to protrude from the optical fiber tape (6). plurality of V grooves (5) are formed at the front edge side of the slave side optical fibers (3), a groove formed member 1 which has the master optical fiber (4) fixed in the V grooves thereof is provided. The master optical fiber (4) is caused to move in the X and Y directions in the drawing, integral with the groove-formed member (1) by a master movement mechanism 25, whereby the connection end face side of the slave side optical fibers (3) is selectively inserted in the V groove (5a), and the master optical fiber (4) and slave side optical fibers (3) are optically connected to each other in a switchable state by the master optical fiber (4) being opposite the connection end face of the slave side optical fibers (3) in the V groove (5a). When they are optically connected to each other, the connection end face sides of the master optical fiber (4) and the slave side optical fibers 3 are pressed to, pinched in and retained in the V groove (5a) by a pressing member.
