Patent ID: 7646947

Claim:
An optical switch, comprising: an alignment head having a base and a cover, wherein the base has a first V-groove, a second V-groove, and a trench linked to the first and the second V-grooves; a first fiber mounted in the first V-groove; a second fiber mounted in the second V-groove, wherein the cover is mounted on the base to secure the first and the second fibers, respectively; a third fiber having an end located in the trench and aligned to an end of the first fiber; a wedge located beside the base and having an incline; and a displacing means set under the wedge, wherein as the end of the third fiber is aligned to the end of the first fiber, the displacing means is capable of moving the wedge in a first direction and applying a component force in a second direction through a contact to the incline of the wedge to push the third fiber, so as to move the end of the third fiber in the trench in the second direction and to align the end of the third fiber to the end of the second fiber, and wherein the first and the second V-grooves are arranged in the second direction; and as the end of the third fiber is aligned to the end of the second fiber, the displacing means is capable of moving in a third direction opposite to the first direction, such that the incline of the wedge does not push the third fiber, and the end of the third fiber moves in a fourth direction opposite to the second direction to again align the end of the third fiber to the end of the first fiber.
