Abstract

An optical waveguide component includes a substrate having a first surface, an optical waveguide disposed on the first surface, a projection formed on the first surface, a glass block including an optical fiber and including a recess into which the projection fits, wherein the optical waveguide and the optical fiber are optically coupled.

First claim

What is claimed is:

1 . An optical waveguide component comprising:
a substrate having a first surface; an optical waveguide disposed on the first surface; a projection formed on the first surface; a glass block including an optical fiber and including a recess into which the projection fits; wherein the optical waveguide and the optical fiber are optically coupled.

2 . The optical waveguide component according to claim 1 , comprising a plurality of said projections, wherein the glass block includes a plurality of said recesses equal in number to the projections.

3 . The optical waveguide component according to claim 1 , wherein the projection has a cylindrical shape, and the recess has a cylindrical shape.

4 . The optical waveguide component according to claim 1 , wherein the optical waveguide is a polymer waveguide.

5 . The optical waveguide component according to claim 1 , wherein the optical waveguide includes:
a first cladding layer disposed on the first surface; a core disposed on the first cladding layer; a second cladding layer disposed on the first cladding layer and the core, and wherein the second cladding layer adheres the first cladding layer and the core to the glass block.

6 . The optical waveguide component according to claim 1 , wherein the optical waveguide includes:
a first cladding layer disposed on the first surface, a core disposed on the first cladding layer, a second cladding layer disposed on the first cladding layer and the core, and wherein a height of the projection is equal to a thickness of the first cladding layer.

7 . The optical waveguide component according to claim 1 , further comprising an optical semiconductor chip mounted on the substrate and optically coupled to the optical waveguide.
