Moving optical-fiber switch experiment

The switch uses a V-grooved connecting device. The mechanism is suitable for a large switch, which is desirable for an optical switching system. A moving fiber is inserted into one of the radially arranged V grooves using the elastic bending force as the drive current. The insertion condition, which realizes stable connection and high durability, is discussed. Switch structure and experimental results are described. Insertion loss was 0.33 dB, and the variation in transmissivity was 3%.
