摘要： A depletion mode thin film semiconductor photodetector comprises a crystalline silicon thin film on an insulating substrate with a source region, a drain region and a thin film light sensing channel region formed therebetween. A gate oxide formed over the channel region and a gate electrode formed on the gate oxide. A p-n junction located parallel to the surface of the substrate and within the thin film functioning as a space charge separation region in the channel. The lower portion of the channel region is a p region extending to the substrate and the upper portion of the channel region is a n region extending to the gate oxide. The channel region functions as a fully depleted channel when the photodetector is operated in its OFF state providing for high dynamic range and large photocurrent operation. The depletion mode thin film semiconductor photodetector with n.sup.+ source and drain regions function as an ohmic contacts to the channel n region forming a thin film transistor. The thin film transistor photodetector has high photoconductive gain at low light intensities when the n channel region is fully pinched off by an applied gate voltage to the gate electrode which is sufficiently negative as compared to the threshold voltage of the photodetector. When the drain region is replaced by a p.sup.+ region functioning as an ohmic contact to the channel p region, a depletion mode gated diode is formed. When the channel region is extended to include a plurality of linearly spaced gate electrodes formed on the gate oxide region with an input diode formed adjacent to the first of such gate electrodes and an output diode formed adjacent to the last of such gate electrodes, the photodetector functions as a charge coupled device.

摘要： A vertical external cavity surface emitting laser (VECSEL) structure includes a heterostructure and first and second reflectors. The heterostructure comprises an active region having one or more quantum well structures configured to emit radiation at a wavelength, λlase, in response to pumping by an electron beam. One or more layers of the heterostructure may be doped. The active region is disposed between the first reflector and the second reflector and is spaced apart from the first reflector by an external cavity. An electron beam source is configured to generate the electron beam directed toward the active region. At least one electrical contact is electrically coupled to the heterostructure and is configured to provide a current path between the heterostructure and ground.

摘要： An implantable product such as an article, device, or system can include analyte and non-analyte containers in parts that can be operated as optical cavities. The product can also include fluidic components such as filter assemblies that control transfer of objects that affect or shift spectrum features or characteristics such as by shifting transmission mode peaks or reflection mode valleys, shifting phase, reducing maxima or contrast, or increasing intermediate intensity width such as full width half maximum (FWHM). Analyte, e.g. glucose molecules, can be predominantly included in a set of objects that transfer more rapidly into the analyte container than other objects, and can have a negligible or zero rate of transfer into the non-analyte container; objects that transfer more rapidly into the non-analyte container can include objects smaller than the analyte or molecules of a set of selected types, including, e.g., sodium chloride. Output light from the containers accordingly includes information about analyte.

摘要： The AlGaN upper cladding layer of a nitride laser diode is replaced by a non-epitaxial layer, such as metallic silver. If chosen to have a relatively low refractive index value, the mode loss from absorption in the non-epitaxial cladding layer is acceptably small. If also chosen to have a relatively high work-function, the non-epitaxial layer forms an electrical contact to the nitride semiconductors. An indium-tin-oxide layer may also be employed with the non-epitaxial cladding layer.

摘要： Sensors can be used to obtain encoded sensing results from objects that have nonuniform relative motion. A photosensor or impedance-based sensor, for example, can obtain sensing results from objects that have relative motion within a sensing region relative to the sensor, with the relative motion being, for example, periodically varying, randomly varying, chirp-varying, or modulated relative motion that completes at least one modulation cycle within the sensing region. Relative motion can be caused by varying objects' speed and/or direction or by controlling flow of fluid carrying objects, movement of a channel, movement of a support structure, movement of a sensor, and/or pattern movement. A fluidic implementation can include shaped channel wall parts and/or a displacement component causing time-varying lateral displacement. A support structure implementation can include a scanner device and a rotary device that respectively control scanning and rotating movement of a movable support structure or of a sensor.

摘要： Nitride semiconductor films, such as for use in solid state light emitting devices and electronic devices, are fabricated in an environment of relatively high nitrogen potential such that nitrogen vacancies in the growing film are reduced. A reactor design, and method for its use, provide high nitrogen precursor partial pressure, precracking of the precursor using a catalytic metal surface, prepyrolyzing the precursor, using catalytically-cracked molecular nitrogen as a nitrogen precursor, and/or exposing the surface to an ambient which is extremely rich in active nitrogen species. Improved efficiency for light emitting devices, particularly in the blue and green wavelengths and improve transport properties in nitride electronic devices, i.e., improved performance from nitride-based devices such as InGaAlN laser diodes, transistors, and light emitting diodes is thereby provided.
