  • Optical module
    Patent number: 6711186
    Abstract: The present invention relates to an optical module for light path conversion, which is used in the fields of optical communications, optical information processing and the like. The optical module of the present invention comprises a surface light emitting element and a light path converting reflective body formed from single-crystal silicon, which has an inclined face on which a light-reflecting film is formed, and is constructed by causing the light that is emitted from the surface light emitting element to be subjected to a light path conversion by the inclined face.
    Type: Grant

  • Optical coupler and a method of producing it
    Patent number: 6112001
    Abstract: An optical coupler wherein on one principal face of an Si single crystal substrate are formed, by etching, grooves for mounting optical fibers and a portion for mounting an optical element that is divided into plural parts, a base substrate, of which coefficient of thermal expansion is substantially identical to that of the optical element, is bonded onto the other principal face of the substrate, and the optical element is mounted on the portion for mounting an optical element.
