摘要： A semiconductor light-emitting device has, in place of a traditional separate cladding layer and contact structure, a non-epitaxial contact and waveguide layer. The non-epitaxial contact and waveguide layer is formed of a conductive material and such that it has a recess therein and over the injection region. Air filling the region together with appropriate choice of material for the non-epitaxial contact and waveguide layer creates desired lateral waveguiding. Metallic silver in one choice for this material. The recess may also be filled with a low-loss material having a refractive index higher than that of the material forming the non-epitaxial contact and waveguide layer. Transparent conductive oxides (e.g., indium tin oxide (ITO), zinc oxide (ZnO), etc.), appropriate metal (e.g., gold), or a composite comprising a conductive oxide and a metal, provide low absorption in the UV and near-IR wavelengths of interest, and are thus good candidate materials for within the recess.

摘要： A semiconductor laser diode with a high indium content is provided with a lattice matched cladding layer or layers. One or both of the cladding layers may comprise bulk aluminum gallium indium nitride in the ratio of AlxGa1-x-yInyN and/or a short period superlattice structures of, for example, a plurality of alternating layer pairs of aluminum gallium indium nitride in the ratio of AlxGa1-x-yInyN and gallium indium nitride in the ratio of GasIn1-sN, providing a multi-quantum barrier (MQB) effect. Lattice matching of the cladding layer(s) and active layer reduce or eliminate strain, and the materials chosen for the cladding layers optimizes optical and carrier confinement. Alternatively, the lattice parameters may be selected to provide strain balanced MQBs, e.g., where the barrier layers are tensile-strained and the well layers compressed.

摘要： A transmissive and/or reflective optical filter can receive input light, which can emanate from objects traveling along paths past the filter, e.g. from biological cells, viruses, colored spots or other markings on documents, and so forth. In response, the filter can provide output light in accordance with a combined transmission function that is approximately equal to a superposition or scaled superposition of a set of simpler transmission functions. The set can include two or more non-uniform transmission functions, a subset of which can be different from each other and positioned relative to each other so that the output light has time variation in accordance with each of the functions in the subset. The subset could include, for example, a random function and a periodic function, a chirp function and a periodic function, or any other suitable combination of two or more simpler functions.

摘要： An implantable product includes an optical cavity structure with first and second parts, each of which can operate as an optical cavity. The first part includes a container with at least one opening through which bodily fluid can transfer between the container's interior and exterior when the product is implanted in a body. The second part includes a container that is closed and contains a reference fluid. The implantable product can also include one or both of a light source component and a photosensing component. Photosensed quantities from the first part's output light can be adjusted based on photosensed quantities from the second part's output light. Both parts can have their light interface surfaces aligned so that they both receive input light from a light source component and both provide output light to a photosensing component.

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： Sensing results from moving objects, e.g. from photosensing emanating light or from impedance-based sensing, can indicate sensed time-varying waveforms with information about objects. For example, a sensed time-varying waveform can be compared with another waveform, such as a reference waveform produced by objects of a certain type, to obtain comparison results indicating motion-independent information about the object; time-scaling can adjust for displacement rate such as speed. Also, a modulation periodicity value can be obtained from a sensed time-varying waveform and used in obtaining information about an object; for example, a periodic modulation frequency can be used with a given time's chirp frequency to obtain phase information about an object's position. Or, where periodic modulation frequency indicates displacement rate, time scaling during comparison can use a scaling factor based on the frequency. Objects can move fluidically as in flow cytometry or through scanning movement, as in document scanning.

摘要： A filter arrangement can transmit and/or reflect light emanating from a moving object so that the emanating light has time variation, and the time variation can include information about the object, such as its type. For example, emanating light from segments of a path can be transmitted/reflected through positions of a filter assembly, and the transmission functions of the positions can be sufficiently different that time variation occurs in the emanating light between segments. Or emanating light from a segment can be transmitted/reflected through a filter component in which simpler transmission functions are superimposed, so that time variation occurs in the emanating light in accordance with superposition of two simpler non-uniform transmission functions. Many filter arrangements could be used, e.g. the filter component could include the filter assembly, which can have one of the simpler non-uniform transmission functions. Time-varying waveforms from sensing results can be compared to obtain spectral differences. The filter arrangement, in a practical commercial embodiment, can be manufactured to be disposable, and used in a point-of-care device for use practically anywhere, at low cost, and can also be implemented in an in-line monitoring system.

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： In response to objects having relative motion within an encoding/sensing region relative to an encoder/sensor that, e.g., photosenses emanating light or performs impedance-based sensing, sensing results can indicate sensed time-varying waveforms with information about the objects, about their relative motion, about excitation characteristics, about environmental characteristics, and so forth. An encoder/sensor can include, for example, a non-periodic arrangement of sensing elements; a longitudinal sequence of sensing elements with a combined sensing pattern that approximates a superposition or scaled superposition of simpler sensing patterns; and/or IC-implemented sensing elements that include photosensing arrays on ICs and readout/combine circuitry that reads out photosensed quantities from cells in groups in accordance with cell-group sensing patterns and combines the readout photosensed quantities to obtain the sensing results. Objects can move fluidically as in flow cytometry, through scanning movement as in document scanning, or in other ways.
