PROBLEM TO BE SOLVED: To provide an optical switch capable of optionally switching N×M optical paths (N and M are positive integers) by constitution of the small number of mirrors. SOLUTION: Plural input side optical fibers 1 are arranged side by side on the end part of a substrate and rotary mirrors 4 for reflecting light from each corresponding input side optical fiber 1 are erected on the substrate 3 in correspondence with respective input side optical fibers 1. Each rotary mirror 4 is arranged on the optical axis of its corresponding input side optical fiber 1 and respective rotary mirrors 4 are arranged in a state respectively shifted to the longitudinal direction of the fibers 1. Plural output side optical fibers 2 are arranged on the light reflection side of the mirrors 4. |
