摘要： A multi-focus optical sensing device for use in bar code scanners, photoelectric sensors and the like is disclosed. To extend the range of detection along the optical axis, without increasing the detection time, the focal point of the light beam is caused to move along the optical axis. A control and modulation circuit varies a current I.sub.f which drives an optical semiconductor serving as a light source. This changes the focal distance of a refraction lattice and so causes the focal position of the light beam emitted by light source to scan along the optical axis. This scan is repeated each time a polygonal mirror scans the light beam over the narrowest width 1/n (where n is an integer) of the bar code lines. A processing unit samples and processes the signal from a photodetector unit while the light beam is being scanned along the optical axis.

摘要： In a reflective photosensor in which a light emitting element and a light receiving element are disposed in a mold resin, a planar optical element (micro Fresnel lens) including a first lens section for projecting a light emitted from the light emitting element toward a sense object in an external space and a second lens section for introducing a reflection light reflected from the sense object to the light receiving element is arranged in the mold resin. Favorably, the light emitting element is a light emitting diode of an edge emitting type and is set in a posture in which the element lies on its side. A reflection mirror is disposed in the model resin to introduce a light emitted from the light emitting diode to the first lens section.

摘要： In a ridge waveguide-type semiconductor light-emitting device, a buried layer is composed of a high-resistance semiconductor material (e.g., amorphous silicon), thereby improving the heat-dissipating characteristic and prolonging lifetime. The buried layer is made higher than the top surface of the ridge, the top surface of the ridge is situated in the resulting recess, and an electrode is formed from the top surface of the ridge to the top surface of the surrounding buried layer to cover the entirety of these surfaces. Making the buried layer higher than the top of the ridge prevents an electrical short circuit for being caused by an electrically conductive bonding agent used in junction-down mounting.

摘要： A semiconductor laser having an internal current restriction includes a (100) face-oriented p-type GaAs substrate treated to have a groove or difference in level having an (n11) A face (n=1-5) as an inclined surface. An AlGaAs: Si layer, an AlGaAs:Be cladding layer, an AlGaAs active layer, and an AlGaAs:Sn cladding layer are grown on the substrate in the order mentioned. Since the Si acts as an n-type material on the (100) face and as a p-type material on the (n11) face, the AlGaAs:Si layer becomes a p-type layer solely in the groove, and it is in this portion that a current path is formed. The laser can be fabricated by molecular-beam epitaxy applied in a single step.
