<P>PROBLEM TO BE SOLVED: To provide an optical device that has superior optical coupling characteristics, by reducing connection loss through improvement in the optical connecting structure between an optical waveguide and optical elements, and to provide a manufacturing method of the same. <P>SOLUTION: An optical device includes an optical waveguide 11, optical elements 22 and 23, and a resin layer 34 disposed between the optical waveguide 11 and the optical elements 22 and 23. The resin layer is formed of a photocurable material alone, or in combination with a thermosetting material, and includes an optical interconnect 34a of high refractive index formed from perimeter for optically connecting the optical waveguide 11 and the optical elements 22 and 23. The optical interconnect has a refractive index higher than that of a region of the resin layer around the optical interconnect. A method for producing the optical device includes providing the photocurable material between the optical waveguide 11 and the optical elements 22 and 23, partially irradiating the photocurable material with light to form the optical interconnect 34a, and secondarily irradiating the overall photocurable material with light to cure the overall resin layer. <P>COPYRIGHT: (C)2007,JPO&INPIT |
