Abstract
An optical waveguide component has a first optical member in which a predetermined first core pattern groove is formed and a second optical member in which a predetermined second core pattern groove is formed, the first and second optical members being combined together so that said first and second core pattern grooves are opposingly overlapped with each other, and the first and second core pattern grooves being filled with a core material.

A method of producing an optical waveguide component, comprising the steps of:
- forming a predetermined core pattern groove in surfaces of first and second optical members by means of press molding;
- sandwiching a material of a high refractive index between faces of said first and second optical members in which a core pattern is formed;
- and
- curing said material of a high refractive index to be formed into a core layer,
- wherein said predetermined core pattern groove is formed in surfaces of said first and second optical members by means of press molding using a molding die in which a base material mainly contains diamond or diamond-like carbon.
A method of producing an optical waveguide component, comprising the steps of:
- forming a predetermined core pattern groove in surfaces of first and second optical members by means of press molding;
- directly bonding faces of said first and second optical members in which a core pattern is formed, to each other;
- filling a liquidus material of a high refractive index into a cavity formed by bonding of said core pattern grooves;
- and
- sealing ends of said core pattern grooves,
- wherein said predetermined core pattern groove is formed in surfaces of said first and second optical members by means of press molding using a molding die in which a base material mainly contains diamond or diamond-like carbon.
