| Research Abstract |
Firstly the fabrication technology ofphotonic crystal resonator was developed using silicon (Si) wafer. And the quality factor of 75,000 was obtained at a resonation wavelength of 1502.9 nm. Next, the fabrication technology of photonic crystal using magneto-optic material, gadolinium gallium garnet (Gd_3G_a5O_12:GGG), was developed by embedding the GGG substrate in the Si wafer. Concerning the magneto-optic switches, the GGG particles are absorbed on the Si ring resonator and the resonation-wavelength shift due to the magnetic field was observed.
