    Abstract: An infrared emitter, which utilizes a photonic crystal (PC) structure to produce electromagnetic emissions with a narrow hand 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: A radiation source including a base, a curved reflector attached to the base, pins passing through the base and within the reflector, and a filament of high emissivity material helically wound about the pins and having opposing ends electrically connected to the pins so that upon passage of electrical energy through the filament, the filament becomes electrically heated and emits infrared radiation.

    Abstract: A device made by 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.

    Abstract: A spectrometer system comprises (i) a slab waveguide characterized as an index of refraction higher than a surrounding medium, and having front surface and a rear surface opposite thereto, the front surface including a input portion for accepting optical radiation, a diffractor portion and an exit portion, (ii) a diffraction grating disposed on said diffractor portion of said front surface, (iii) a detector array aligned adjacent to the exit portion, and (iv) a mirror coated on the rear surface of the waveguide. Radiation transmitted within the waveguide from the input portion is reflected and collimated by the mirror to the granting. Light diffracted from the grating is dispersed to the mirror and reflected toward and through the exit portion and onto the array.
