Patent ID: 7046873

Claim:
An optical switch device comprising: a first substrate; a second substrate arranged to abut the first substrate and having a plurality of fiber-mounting grooves formed thereon adjacent to the first substrate; a plurality of optical fibers arranged in each of the plurality of fiber-mounting grooves of the second substrate and opposing each other at an interval; and an actuator for switching an optical path between the optical fibers by proceeding to and retracting from between the plurality of optical fibers arranged on the second substrate; wherein the second substrate includes a fiber clamp arranged to push the optical fiber toward one of two opposite internal surfaces of the fiber-mounting groove and toward the first substrate; the fiber clamp comprises a spring unit having a rear anchor attached to one internal surface of the fiber-mounting groove and an end extremity movable in width directions of the fiber-mounting groove, and a pushing unit arranged adjacent to the end extremity of the spring unit for obliquely pushing the optical fiber toward the other internal surface and toward the first substrate; and the pushing unit includes an inclined plans formed thereon that is inclined in a thickness direction of the second substrate so as to be brought into surface contact with the optical fiber.
