  • Publication number: 20070058922
    Abstract: Provided are an optical waveguide master and a method of manufacturing the same, which has a 90° optical path change structure and an integrated optical waveguide with a 45° inclined reflection surface. The optical waveguide with the inclined reflection surface manufactured using the optical waveguide master facilitates coupling between the active optical electronic device and the waveguide, thereby perfectly overcoming difficulty in conventional mass production. The optical waveguide makes it possible to accomplish connection between various optical devices and optical circuits, and becomes source technology of an optical printed circuit board (PCB) and a system on package (SOP) in the future.
