摘要： A flat panel display (1001) is based on a new switching technology for routing laser light from a laser light source (1000) through an array of optical energy routers (1008) among a set of optical waveguides (1014) and coupling light toward the viewer. The switching technology is based on poled electro-optic structures. The display technology is versatile enough to cover application areas spanning the range from miniature high resolution computer display to large screen displays for high definition television (HDTV) formats. The invention combines the high brightness and power efficiency inherent in visible semiconductor diode laser sources with a new waveguide electro-optical switching technology to form a dense two-dimensional addressable array of high brightness light emissive pixels.

摘要： A compact display system including a viewing surface (30); a beam steering mechanism (28); a source of light (26) remote from the viewing surface (30) and the beam steering mechanism (28); and at least one waveguide (24) connecting the source of light with the viewing surface (30) for transmitting illumination from the source of light to the viewing surface (30). The beam steering mechanism (28) is associated with the waveguide (24) and the viewing surface (30) for scanning illumination transmitted by the waveguide onto the viewing surface. There is a modulator (32) for modulating the source of light; and a subsystem for synchronizing the modulator with the beam steering mechanism, but only the distal end of the waveguide and the beam steering mechanism are located near the viewing surface resulting in a more compact display which can be mounted on a pair of eyeglasses.

摘要： In a polarization rotator device, a thin-film magneto-optic medium (2) is magnetized by a thin-film magnet (4). To serve as an optical isolator, the device may include polarizers (51, 52). In such an optical isolator, in which the magneto-optic medium (2) was formed as a Bi-YIG triple-layer structure, and the thin-film magnet (4) as a single-crystal iron-cobalt layer, an extinction ratio better than -20 dB was realized.

摘要： A scanner is disclosed which uses an electro-optic deflector (12; 112) to deflect a light beam onto a receiving medium (18; 118). The deflector (12; 112) comprises a substrate (20; 120) formed of an optical material and a thin film optical channel waveguide (22; 122) fabricated on a top surface thereof. A light beam is supplied to the waveguide (22; 122) along an optical axis (37; 137) in the waveguide (22; 122). An array of parallel metallic electrodes (24; 124) are formed adjacent to the waveguide (22; 122). Each of the electrodes (24; 124) is adapted to receive a voltage independently of the other electrodes. When a voltage is supplied to an electrode, a local variation in the index of refraction of the waveguide (22; 122) occurs across the thickness of the waveguide, and this local variation is used to effect the radiation of the beam into the substrate (20; 120). In order to use the waveguide to scan a light beam across the receiving medium (18; 118), the light beam is supplied to the waveguide (22; 122) in a direction normal to the electrodes (24; 124), and a voltage is sequentially supplied to the electrodes.
