Title:
LIGHT GUIDE DEVICE, OPTICAL WAVEGUIDE DEVICE, MULTI-WAVELENGTH LIGHT SOURCE MODULE, AND METHOD FOR MANUFACTURING OPTICAL WAVEGUIDE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/082347
Kind Code:
A1
Abstract:
This optical waveguide device is provided with: a substrate; an optical waveguide path which is provided on the substrate, has an incidence opening and an emission opening for the light, and guides light from the incidence opening to the emission opening; a first clad layer which is disposed between the optical waveguide path and the substrate, is in contact with the optical waveguide path, and has a smaller refractive index than the optical waveguide path; and a second clad layer which is provided on the opposite side of the first clad layer on the optical waveguide path, is in contact with the optical waveguide path, and has a smaller refractive index than the optical waveguide path. The optical waveguide path extends and is composed of the same material from the incidence opening to the emission opening. In at least a portion of the optical waveguide path, the surface of the optical waveguide path on at least one side in the width direction of the optical waveguide path is in contact with air.
