Abstract
Disclosed herein is a printed circuit board for an optical waveguide, including a base board, and an optical waveguide formed on the base board. The optical waveguide includes a lower clad layer formed on the base board, an insulation layer formed on the lower clad layer and having a core-forming through-hole, a core part formed on a region of the lower clad layer, which is exposed through the through-hole, and an upper clad layer formed in the through-hole and on the insulation layer.
Claims14
A method of manufacturing a printed circuit board for an optical waveguide, comprising:
- forming a lower clad layer on a base board;
- forming an insulation layer, having a core-forming through-hole therein, on the lower clad layer;
- filling the through-hole in the insulation layer with a core material;
- forming a core part by patterning the core material received in the through-hole;
- and
- forming an upper clad layer in the rest through-hole except for the core part and on the insulation layer.
A method of manufacturing a printed circuit board for an optical waveguide, comprising:
- forming a lower clad layer on a base board;
- forming a molding film, having a core-forming through-hole therein, on the lower clad layer;
- filling the through-hole in the molding film with a core material;
- forming a core part by patterning the core material received in the through-hole;
- removing the molding film;
- and
- forming an upper clad layer on the lower clad layer such that the upper clad layer surrounds the core part.
