OPTICAL PRINTED CIRCUIT BOARD HAVING OBTUSE-ANGLE EMBEDDED OPTICAL-FIBER WAVEGUIDE

摘要

PURPOSE: An optical printed circuit board in which optical-fiber waveguide with an obtuse-angle is embedded is provided to easily arrange light by preventing the breakdown of the optical-fiber waveguide. CONSTITUTION: An optical-fiber waveguide(201) is stacked on the inside of an optical printed circuit board(204) and transmits optical signal. An optical path changing unit(202) changes the optical path into an obtuse-angel on both ends of the optical-fiber waveguide. The optical-fiber waveguide with the curvature of the obtuse-angel is embedded into the optical printed circuit board.
