Abstract :
As a novel application of integrated optics, a detection method of microdisplacement is proposed and its first demonstration is reported. The sensor has the Michelson interferometer configuration composed of an optical waveguide hybrid coupler. The operation was confirmed by building and testing the sensor using a Ti-diffused LiNbO3 waveguide.
