  • Printed circuit board waveguide
    Patent number: 6370291
    Abstract: A printed circuit board is made of a light transmitting material and is used as a waveguide for light. The board may be coated on both surfaces with a light-reflecting material to improve waveguiding properties. Such a board is operative to replace the microlens and optical fiber common in laser diode packages to form an optical path to deliver optical energy to some sensor position. A sensor of optical energy need only be coupled to a window in one of the coatings or positioned at the edge of the board.
