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.

摘要： A method and structure for adjusting the wavelength output of a semiconductor device is described. In the method, the hydrogen concentration in an active region of the semiconductor device is adjusted either during fabrication or after the device has been fabricated. The adjustment provides a simple technique for fine tuning many device types including regular lasers and VCSEL structures. The adjustment also allows for mass production of lasers of many different frequencies on a single wafer substrate, a system particularly desirable for wavelength division multiplexing systems.

摘要： Lasers, such as in laser structures, can include two or more semiconductor structures that are substantially identical or that include the same semiconductor material and have substantially the same geometry, such as in closely spaced dual-spot two-beam or quad-spot four-beam lasers. The lasers can also include differently structured current flow or contact structures or different wavelength control structures. For example, current flow or contact structures can be differently structured to prevent or otherwise affect phase locking, such as by causing different threshold currents and different operating temperatures. Exemplary differences include that one laser's semiconductor structure can have an isolated area that does not receive electrical current from a covering conductive layer; conductive layers of two layers can have different thicknesses or lengths; one laser can have a patterned layer with high electrical resistance between its semiconductor structure and a conductive layer; or one laser's semiconductor structure can include regions of high electrical resistance adjacent its contact structure.

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 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.
