発明の名称 (英語) OPTICAL WAVEGUIDE DEVICE, PHOTOELECTRIC CONVERSION DEVICE, ARCHITECTURAL STRUCTURE, ELECTRONIC APPARATUS AND LIGHT-EMITTING DEVICE
発明の概要(英語) An optical waveguide device comprises a planar optical waveguide 10, a transparent layer 20 located on a principal surface thereof and having refractive index anisotropy, and a reflecting mirror array 30 located thereon. Reflecting mirrors 31 of the reflecting mirror array 30 reflect three-dimensional space propagation light entering from outside and causes the reflected three-dimensional space propagation light to enter the layer 20 having refractive index anisotropy. The layer 20 having refractive index anisotropy permits transmission of light that enters the layer 20 having refractive index anisotropy by the reflection of the three-dimensional space propagation light by the reflecting mirrors 31, and restricts transmission of light that enters the layer 20 having refractive index anisotropy after entering the planar optical waveguide 10 through the layer 20 having refractive index anisotropy and then being fully reflected by the back surface of the planar optical waveguide 10. A photoelectric conversion device is configured by providing a semiconductor layer for photoelectric conversion at an end of the planar optical waveguide 10.
