Abstract
An optical fiber mounting waveguide device includes a substrate, an optical fiber mounting groove provided on a part of the substrate for mounting an optical fiber, an under cladding layer and a core sequentially formed on the substrate, and an over cladding layer formed on the core, the over cladding layer having an end surface facing to the optical fiber mounting groove, and wherein the core and the under cladding layer are protruded toward the optical fiber mounting groove with respect to the end surface of the over cladding layer.
Claims9
An optical fiber mounting waveguide device comprising:
- a substrate;
- an optical fiber mounting groove provided on a part of the substrate for mounting an optical fiber;
- an under cladding layer and a core sequentially formed on the substrate;
- and
- an over cladding layer formed on the core, the over cladding layer having an end surface facing to the optical fiber mounting groove, and
- wherein the core and the under cladding layer are protruded toward the optical fiber mounting groove with respect to the end surface of the over cladding layer.
A method for fabricating an optical fiber mounting waveguide device, comprising:
- forming an optical fiber mounting groove on the optical fiber mounting waveguide device for mounting an optical fiber;
- forming an under cladding layer and a core sequentially on a substrate at a position facing to the optical fiber mounting groove;
- coating a cladding material on the under cladding layer and the core;
- providing a mask pattern for covering a part of the over cladding layer at the position facing to the optical fiber mounting groove;
- and
- exposing the cladding material to provide an over cladding layer,
- wherein the core and the under cladding layer are protruded toward the optical fiber mounting groove with respect to an end surface of the over cladding layer.
