| Research Abstract |
A TiO_2 optical waveguide is one of the most suitable candidates for the microfabrication because of the high refractive index and the transparency from infrared to visible region. However the microfabrication scheme has not been developed and the optical properties of the microfabricated waveguide have been never evaluated. We demonstrate the fabrication of micrometer-scale TiO_2 waveguides and report the optical properties. We observed that the microfabricated TiO_2 channels successfully guided red light(632 nm) along linear and Y-branched patterns. The propagation loss of the linear waveguide was 9. 7 dB/ cm.
