摘要： A fluidic structure includes a channel and along the channel is a series of sensing components to obtain information about objects traveling within the channel, such as droplets or other objects carried by fluid. At least one sensing component includes a set of cells of a photosensor array. The set of cells photosense a range of photon energies that emanate from objects, and include a subset of cells that photosense within subranges. A processor can receive information about objects from the sensing components and use it to obtain spectral information. The processor can perform an initial analysis using information from one set of sensing components and, based on the results, control a fluidic device in the channel, such as a gate, to retain objects, such as for concentration and more detailed analysis by other sensing components, or to purge objects from the channel.

摘要： A display apparatus includes a luminescent screen having pixels formed from blue, green and red luminescent material that are selectively activated by a laser beam to generate a full color image. The display utilizes a closed loop laser scanning/modulating arrangement in which a Position Sensitive Device (PSD) located next to the screen is used to determine the location of the impinging beam, and to transmit timing/location data to the laser addressing system. The laser addressing system uses the timing/location data to adjust and/or modulate the laser beam, thereby generating high-energy beam pulses that activate the selected pixels. The PSD includes vertical strips located along the side edges of the screen, or a sheet that is located behind the screen and accessed, for example, by way of slits or apertures formed in the screen material. The PSD sheet is coupled to an optional power source to form a photon-multiplication device.

摘要： An optical semiconductor device such as a light emitting diode is formed on a transparent substrate having formed thereon a template layer, such as AlN, which is transparent to the wavelength of emission of the optical device. A variable period variable composition superlattice strain relief region is provided over the template layer such that the composition of the strain relief region approaches or matches the composition of the regions contiguous thereto. For example, the Al content of the strain relief region may be tailored to provide a stepped or gradual Aluminum content from template to active layer. Strain-induced cracking and defect density are reduced or eliminated.

摘要： An integrated circuit includes a photosensor array with subrange cells that photosense within respective subranges of an energy range. An optical signal and the array move relative to each other, and, for segments of their relative movement, sets of subrange cells photosense within subranges that are different. For example, a scanning device can cause relative scanning movement. The optical signal can be produced by illuminating a two-dimensional object. The photosensed quantities for a part of the optical signal can be used to produce spectral information for the part.

摘要： A compact sensor for detecting the presence of biological or chemical species includes a microdisk laser and a wavelength shift detector. The microdisk laser is coated with a biological or chemical recognition element, which binds preferentially with a target analyte. Because the recognition element and the target analyte adhere to the sidewall surface of the microdisk laser, they increase the effective diameter of the laser, which shifts the output wavelength by a detectable amount. The presence of a wavelength shift indicates the presence of the target analyte, and the magnitude of the wavelength shift corresponds to the mass load of the target analyte on the sidewall surface of the microdisk laser.

摘要： A grating-outcoupled microcavity disk resonator has whispering gallery modes existing in a nearly circular resonator. Light is outcoupled by providing a grating region in the plane of the grating-outcoupled microcavity disk resonator. The grating region provides an outcoupling or lass mechanism that symmetrically interacts with the clockwise and counterclockwise whispering gallery modes, thereby making the resonator capable of surface emission.

摘要： A method of avoiding device failure caused by facet heating is described. The method is particularly applicable to a semiconductor laser. In the method, a semiconductor laser facet including GaAsN is hydrogenated such that the bandgap within the facet is greater than the bandgap in the active region of the InGaAsN laser. The increased bandgap reduces absorption of light in the facet and the associated heating that results.
