| titleOfInvention | Integrated optic disc pickup |
| abstract | An integrated optic disc pickup comprising an optical waveguide in the form of a insulation layer provided on the surface of a substrate, a semiconductor laser disposed outside the waveguide, a beam splitter of the transmission type and a Luneburg lens provided for the path of propagation of a laser beam from the semiconductor laser through the waveguide and arranged in the order mentioned in a direction away from the laser, a transmission grating provided on the path through the waveguide to be followed by the laser beam upon having its direction changed by the beam splitter after emanating from the laser, passing through the beam splitter and the Luneburg lens, being reflected from an optic disc disposed outside the waveguide and passing through the Luneburg lens, and first and second photodetectors disposed on the paths of propagation through the waveguide of two portions of the laser beam divided by the diffraction grating. |
