CONSTITUTION:Laser light 6 is conducted from a grating optical coupler 3 to an optical waveguide layer 2 formed by the thermal diffusion of Ti and proton on an x-plate or y-plate LiNbO3 crystal substrate 1 so as to result an absorption peak of infrared absorption spectrum of OH group due to proton to be in a range between 3,480-3,503cm wave number. The waveguided light is diffracted by a phase lattice by impressing a voltage to a comb-shaped electrode 11 for the electrooptic effect, and is taken out to the outside from a grating optical coupler 4. In this case, a high diffraction efficiency as high as 90% is obtd. by impressing 6V voltage on the electrode 11.,下面是Thin film optical element专利的具体信息内容。
