Abstract
There is disclosed an optical switch consisting of a support substrate, a movable raw optical fiber, a fixed raw optical fiber, a magnetic member for the movable raw optical fiber, and a leaf spring. The fibers are disposed in a V-shaped groove formed in the substrate. The magnetic member is actuated by an electromagnet disposed above the substrate. The leaf spring pushes the movable raw optical fiber into the V-shaped groove. The structure of the switch is relatively simple. Since the movable raw optical fiber is pushed using the leaf spring, the switch is less affected by the assembly accuracy than conventional. It is easy to make adjustments during assembly. Consequently, high-performance, low-cost, optical switch that can be mass-produced can be offered.
