    摘要: An optical pickup device includes a laser source for emitting linearly polarized light; an objective lens for focusing source light received from the laser source on an optical information storage medium; a photodetector for receiving signal light reflected from the medium for converting the signal light into an electric signal. The photodetector includes at least a photosensor, a planar optical waveguide formed on the photosensor for propagating the signal light therethrough, diffraction grating for diffracting the signal light propagating through the waveguide, and an incidence coupler provided on the waveguide for reflecting the source light emitted from the laser source and receiving signal light obtained through the objective lens from the medium. A plane of incidence including a normal to a surface of the incidence coupler and the optical axis of the source light is formed at an angle range of 5 to 85 degrees to a plane of polarization of the source light having an electric field vector of the optical axis and the source light. Thus, the direction of polarization of the signal light from the medium is also formed at an angle range of 5 to 85 degrees to the plane of incidence for the signal light to thereby detect the presence/absence of information. This reduces the size of the pickup device.

    摘要: An information processing apparatus such as an optical disc device which is provided with an integrated photo detector for transducing a reflected light beam from an optical information medium to an electric signal. The integrated photo detector used in the apparatus comprises a substrate; an optical guide formed on the substrate; and a plurality of integrated photo detecting sections each including a grating coupler for guiding the reflected light beam to the optical guide, and a photo detecting unit for detecting a guided light beam in the optical guide. The use of this integrated photo detector results in increasing error tolerance relative to incident angle and incident position to improve the incidence efficiency, thereby elevating the reliability of the apparatus.

    摘要: The present invention provides a sheet-shaped material containing an RFID thread. The RFID thread comprises a strip-shaped film onto one side of which a semiconductor chip containing plural bits of memory and provided with an antenna wire is bonded. The strip-shaped film has plural openings formed therethrough except where the semiconductor chip is bonded. Since intertwining occurs between paper fibers via the openings, the RFID thread is strongly fixed in the paper.
