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： In an optical scanning type tunneling microscope, reference light is prepared in addition to light used to be projected to a sample, and this reference light and also light picked up from an optical probe are caused to interfere with each other. As a result, phase information of light about a region having a very smaller dimension than a wavelength of the light irradiated from alight source can be acquired.

摘要： Branch-point image data has coordinates added thereto according to the distance from a branch point such as an intersection. When the vehicle is within a predetermined distance from a branch point on a suggested route, the coordinates of the present position of the vehicle and the coordinates added to the branch-point image data are compared to locate the present position on the image data, and a present-position mark is displayed superimposed on the branch-point image data. The displayed present-position mark moves according to the distance between the vehicle and the branch point.
