| 英文摘要 | An optical information record/read apparatus comprises a light source for emitting light, a converging optical system for converging the emitted light from the light source on the optical record medium so that the converged light is reflected by the optical record medium, and an optical waveguide element having a waveguide layer. A light coupling system is provided for coupling the reflected light from the optical record medium with the waveguide layer so that the light coupled with the waveguide layer is then propagated, as a guided light, within the waveguide layer. At least a part of the light coupling system is integrally formed with the optical waveguide element. A light detecting system for detecting the guided light propagated within the waveguide layer is integrally formed with the optical waveguide element. A waveguide reflection optical system for reflecting the guided light within the waveguide layer toward the light detecting system while converging the same is formed as a part of an end face of the waveguide layer. |
