ln Wavelength Division Multiplexing (WDM) technology, higher speed transmission and more channel numbers expand the transmission capacity. For its application, optical communication devices are required to be smaller and to have higher performance. We have developed the ultrasonic micro-motor and the micro thermoelectric device for Watch use. We are trying to apply these micro-mechanical devices to optical communication devices, which are variable optical attenuator, laser diode dependent on temperature, and so on. These micro-mechanical devices are expected to be new sources for the application in the optical communication field.
