Abstract:
1. An optical waveguide device comprising: a substrate on which an optical waveguide is formed; a groove formed in a groove-forming face at an end of the substrate along a light transmitting direction of the optical waveguide, wherein a connection end of an optical fiber is fitted into the groove; and an adhesive layer provided on the groove-forming face of the substrate for embedding the connection end of the optical fiber such that the adhesive layer substantially covers an outer circumferential face of the optical fiber outside of the groove, wherein the adhesive layer has an upper face that is almost parallel to the groove-forming face of the substrate and is above the groove-forming face, the whole upper face of the adhesive layer is substantially flat, and the adhesive layer has a thickness such that the adhesive layer covers the outer circumferential face of the optical fiber outside of the groove.
