Abstract: The motor vehicle headlight has semiconductor lasers as light source (1) of the motor vehicle headlight, and a light modulator which modifies the directional characteristic of the light. The light is radiated from the semiconductor lasers. The light modulator has a micro-electromechanical optical system, particularly a micromirror array, a liquid crystal display (LCD) panel, a liquid crystal on silicon (LCoS) panel or a grating light value.

Abstract: A transparent material, especially a 6 inch glass wafer, is divided into strips (2) by sawing. Cut surfaces are smoothed. The strips are bonded to a substrate (4), e.g. a silicon wafer. The substrate and bonded strips are divided, in order to make the optical components required. Opposite planar surfaces of the glass are parallel; at least one of them has an anti-reflective coating. At least one has a reflective coating. The cut strips are arranged so that two or more cut surfaces are smoothed together, before bonding. The smoothed strips are bonded to the substrate by their smoothed, cut sides. The substrate is made of silicon. Anodic bonding, or alternatively low-temperature bonding, is used. Strips are fastened at right angles to the surface of the substrate, and are mutually-parallel. Spacers are used to align the strips on the substrate. These are removed before dividing the substrate with its bonded strips. The substrate and bonded strips are bodily-divided, to make carriers with optical elements, in such a manner that after division, only one optical element is present on each carrier. Alternatively, the division may leave numbers of optical elements (cut from their respective original strips) on a single carrier. This stage of division is also achieved by sawing.

Abstract: The laser has a modes selective device provided for rejection of higher resonator modes of the laser. The selective device is fixedly connected with a semiconductor body (3). The selective device is arranged in an optical path of a pumping radiation source. An optical unit (11) is used as a heat sink and provided in thermal contact with a radiation passage surface of the body. A non-optical linear crystal is arranged in a resonator of the laser. The optical unit is provided for frequency selection of the laser radiation passing through the optical unit.

Abstract: The semiconductor laser has a semiconductor chip (1) and at least two resonator reflectors (4). A pump laser (10) optically pumps the laser with a pump power which is modulated with a modulation frequency whilst the laser resonator has a resonator length which is adapted to same. The pump power is preferably modulated so that it does not drop below a laser threshold of the pump laser during the modulated operation. The pump laser is mounted outside of the semiconductor chip.

Abstract: Optoelectronic component has a support body (14), an optoelectronic transmitter (16) of coherent light and a receiver (20) mounted on the support. An optical beam splitter (30) divides the transmitted light beam (a) into reference (b) and measurement (c) beams. The latter two are combined to form an interference beam (d) that is incident on the receiver. The beam splitter is held at a distance from the support by means of a spacer (26, 28). The invention also relates to use of the inventive component in a writing recognition system and in the tip of a wand type reader.

Abstract: The device has a beam divider (2) and filters and detectors (8,9) in the partial light paths (3,4) after the beam divider. Each filter has a doubly refracting layer (5,6) for converting linearly polarized light into elliptically polarized light and a layer (7) after it in the direction of incidence of a material in the cholesterinic phase. The filters differ in dependency on transmission of the polarization direction of the incident light. AN Independent claim is also included for the following: a method of manufacturing an inventive device
