    Abstract: An infrared emitter, which utilizes a photonic crystal (PC) structure to produce electromagnetic emissions with a narrow band of wavelengths, includes a semiconductor material layer, a dielectric material layer overlaying the semiconductor material layer, and a metallic material layer having an inner side overlaying the dielectric material layer. The semiconductor material layer is capable of being coupled to an energy source for introducing energy to the semiconductor material layer. An array of surface features are defined in the device in a periodic manner or quasi-periodic. The emitter device is adapted to emit electromagnetic energy having spectral characteristics determined by parameters of the periodically distributed surface features, the parameters including shape, size, depth, distribution geometry, periodicity, material properties and defects.

    Abstract: An absorption spectroscopy apparatus including a sample cell having a central axis, and a side wall coaxially positioned about the axis. The side wall defines a generally circular cross-section of the cell as taken along a plane extending perpendicular to the axis, wherein the generally circular cross-section of the sample cell has an average radius. The side wall includes a plurality of light reflective segments arrayed about the axis, wherein each reflective segment has a cross-section taken along a plane extending perpendicular to the axis of the cell that is concave with respect to the axis. The concave cross-section of each segment has an average radius that is unequal to the average radius of the generally circular cross-section of the sample cell. Among other aspects and advantages, the apparatus of the present disclosure is able to use incoherent, non-collimated light sources while maintaining high optical throughput efficiencies.

    Abstract: An absorption spectroscopy apparatus having a fluid inlet and a fluid outlet. The apparatus includes a sample cell including an axis, a side wall having at least one curved reflective surface arrayed about the axis and facing inwardly with respect to the cell such that a beam of energy directed against a predetermined location on the reflective surface is reflected back and forth off the reflective surface and remains in substantially the same plane while inside the cell, and at least one port in the sidewall. The apparatus also includes at least one source/detector reflector having a curved profile in a plane extending perpendicular to the axis of the cell. The reflector is positioned with respect to the port of the cell to reflect energy through the port of the cell and against the predetermined location on the reflective surface of the side wall of the cell.

    Abstract: A process of making strain-free, heavily carbon-doped p-type epitaxial layers for use in high performance devices and at least one such device so made. The process essentially includes the epitaxial deposition of a strain-free, carbon-doped p-type layer in a GaAs HBT device to form the base layer thereof in a manner that includes the balancing of the strain of the crystal lattice structure caused by the carbon doping by co-doping the base layer with an isovalent and isoelectric dopant. The co-doping also improves device performance. It also effects alloy hardening, which inhibits further defect formation, improves mobility and carrier lifetime of the base layer and, by narrowing the energy gap, it improves ohmic contact formation.
