摘要： A micromachined pellicle beam splitter and method of manufacture thereof are disclosed. In one embodiment, the beam splitter includes a silicon frame with a silicon nitride membrane attached to the frame and covering an opening through the frame. Other materials may be utilized, however, the coefficient of thermal expansion (CTE) of the membrane should be greater than that of the frame. The beam splitter may be manufactured by coating a silicon substrate with a layer of silicon nitride, patterning an opposite side of the silicon substrate with a photoresist or a metallic layer to define an opening an etching an opening through the substrate to the silicon nitride with either a dry etch or wet etch technique. An improved tunable laser module incorporating the micromachined pellicle beam splitter and a method of tuning a laser diode are also disclosed.

摘要： A low-profile Wireless Display Tag (WDT) fits within the confines of a retail store display shelf-edge C-channel. The WDT may also be used to tag high-value retail item units where it can simultaneously function as a price tag, and an anti-theft device. The invention provides for bidirectional communication between the WDT and a central database. The invention uses a low profile antenna that may be painted onto a surface within the WDT. The WDT is capable of displaying graphics or variable format alphanumeric characters and the placement of display items is user programmable. The WDT uses an RF integrated Circuit (RFIC) that combines the backscatter RF communications method, amplified backscatter RF communications method and the active RF communications method.

The laser comprises first and second reflectors defining an external cavity, and a compensating member coupled to at least one of the reflectors and configured to thermally position one reflector with respect to the other reflector. The compensating member may be coupled directly to the first reflector and configured to position first reflector with respect to said second reflector. The thermal positioning may be carried out by a thermoelectric controller operatively coupled to the compensating member and configured to thermally adjust the compensating member by heating or cooling thereof. The laser apparatus may comprise a gain medium having first and second output facets and emitting a coherent beam from the first output facet along an optical path. The first reflector is positioned in the optical path, with the second output facet and first reflector defining an external cavity. The compensating member may be thermally conductive and have a high coefficient of thermal expansion.

摘要： A pair of compensation lenses which provide an adjustable amount of spherical aberration. Each compensation lens has an external surface and an internal surface. The internal surfaces face each other and define an air gap spacing between them. The external surfaces are preferably planar. The internal surfaces are purely aspheric and therefore have an absence of spherical power and an absence of spherical curvature. The amount of spherical aberration compensation is determined by adjusting an air gap spacing between the internal surfaces. The spherical aberration provided by the lenses can be negative, positive, or zero. For compensation of negative spherical aberration present when focusing light into a data storage medium, the compensation lenses should provide positive spherical aberration. The absence of spherical power characteristic of the compensation lenses allows them to be located far from an objective lens which requires spherical aberration compensation. Also, the absence of spherical power renders the focusing characteristics of an optical system independent from the air gap spacing thickness. Further, absence of spherical power renders the numerical aperture of the optical system unchanged by variations in air gap spacing.

摘要： A telescoping floor seal assembly comprising an attachment portion adapted to be mounted to a bottom edge of a vertically displaceable partition, and a displaceable sealing portion slideably mounted within the attachment portion for relative displacement therewith between a fully collapsed position and a fully extended position and described. The displaceable sealing portion has at least one longitudinal sealing edge member at a base thereof for contacting a floor when the vertical partition is displaced to a closed position. The attachment portion is substantially vertically displaceable with the vertically displaceable partition while the sealing edge member of the displaceable sealing portion remains in sealing contact with the floor within a predetermined displacement range of vertical movement of the vertical partition. The telescoping floor seal assembly thereby accommodates live load deflections of the vertically displaceable partition without compromising the seal formed between the floor and the telescoping floor seal.

摘要： The present invention is a combination non-imaging concentrator in which at least one surface or volume is incorporated as an optical element to increase obliquity of reflection at walls of a light guide. The combination non-imaging concentrator may be used in a solar energy system to receive solar radiation from optical components and then output the solar radiation to a photovoltaic cell for conversion to electricity. One or more lenses may be formed integrally with the light guide, or may be used in conjunction with the light guide as separate components.
