OPTICAL SWITCH APPARATUS AND CALIBRATION METHOD FOR OPTICAL SWITCH APPARATUS

PROBLEM TO BE SOLVED: To provide an optical switch apparatus having a stable characteristic. SOLUTION: The optical switch apparatus 100 has: one inputting optical fiber 112; a plurality of outputting optical fibers 114 that output light; one detecting optical fiber 116; an optical switch optical system composed of a collimator lens 122, a convergent lens 124, a convergent lens 126, a convex lens 132, a convex lens 134, a grating 136 and a movable mirror 140; a memory 176 which holds a control value relating to the movable mirror 140; a mirror drive circuit 180 which drives the movable mirror 140 in accordance with the control value; a PD 172 optically coupled to the detecting optical fiber 116; and an adjusting circuit 178 which can read and write the control value stored in the memory 176 and can adjust the control value on the basis of an output from the PD 172.
