Patent JP-H03214107-A (JP)
Title: Optical waveguide
Inventor: IWASAKI MASAAKI
IPC: G02B6/12
Filed: 1990-01-18
Abstract: PURPOSE:To increase the refractive index of a substrate surface and to decrease the dependency of a loss on polarization by subjecting at least the part of the optical waveguide adjacent along the curved part of the waveguide to outer diffusion from the substrate surface. CONSTITUTION:The bent waveguide 2 of Ti is formed by depositing a Ti film on the crystal substrate 1 and subjecting the Ti film, which is patterned by a process for the working, such as photolithography, to the thermal diffusion. The thermal diffusion is executed by heating the crystal substrate 1 in a vacuum or inert gaseous atmosphere to release Li2O from the crystal surface to the outside, thereby forming a high-refractive index layer 3. The refractive index to extraordinary light is increased as the Li2O is released to the outside at this time. The confinement of the extraordinary light in a horizontal direction is weakened in this way and the difference in the radiation loss between the ordinary light and the extraordinary light is decreased. The dependency of the loss of the optical waveguide on the polarization is thus decreased.
