摘要： The disclosure is directed to glass frits materials containing phosphors that can be used in LED lighting devices and for methods associated therewith for making the phosphor containing frit materials. Suitable non-lead glasses have a composition, in mol %, in the range of 20-24% K2O, 8-12% ZnO, 2-6% Al2O3, 35-41% B2O3 and 22-28 SiO2. Suitable leaded glasses have a composition, in wt %, in range of 72-79% PbO, 8-13% Al2O3, 8-13% B2O3, 2-5% SiO2 and 0-0.3% Sb2O3. Commercial high-lead glass can be used in practicing the disclosure. Among the unique advantages are the ability to blend two or more phosphors within the same frit layer which will yield a multi-phosphor-containing glass after firing; the ability to deposit the phosphor onto a substrate into a desired geometric pattern; and the fluorescing layer can be applied to the active plane, with the glass serving as protective substrate.

摘要： Wavelength tunable light sources and methods of operating the same are described. In one aspect, a wavelength tunable light source includes a resonant light path, an optical gain medium, an optical grating, a first acousto-optic deflector, and a second acousto-optic deflector. In another aspect, a light source has a resonant light path containing first and second acousto-optic devices for tuning an output light beam over a specified frequency range with an output wavelength profile. The first acousto-optic device is driven with a first signal having a first time-varying frequency profile. The second acousto-optic device is driven with a second signal having a second time-varying frequency profile, wherein the second time-varying frequency profile differs from the first time-varying frequency profile by an amount substantially proportional to a time rate is of change of the output wavelength profile. In this way, the output light beam is tunable over the specified frequency range without observable hopping between longitudinal modes.

摘要： The frequency-selective optical multiplexer comprises, an LC polarization controller, a spectral demux/mux and input/output optics including two ports, a first optical path spatially separated from a second optical path and polarization-dispersive optics. The polarization dispersive optics are disposed between the ports and the optical paths; generate from an optical signal a pair of polarization components, composed of a first polarization component and a second polarization component having orthogonal polarizations; and output the first and second polarization components via the first and second optical paths, respectively. The first and second polarization components have first and second polarizations when the optical signal is received at one port, and have the second and the first polarizations, respectively, when the optical signal is received at the other port. The spectral demux/mux generates first pairs of spatially-separated spectral components from a first pair of orthogonal polarization components received from the input/output optics, outputs the spectral components to the polarization controller, receives respective second pairs of spectral components from the polarization controller, and spatially overlaps the second pairs of spectral components to generate a second pair of polarization components. Either the first pair or the second pair of polarization components passes between the spectral demux/mux and the input/output optics via the optical paths. The polarization controller receives the first pairs of spectral components at a zero angle of incidence, and rotates the polarizations of each of them individually and selectively through 0° or 90° to generate one of the second pairs of spectral components.

摘要： A light source for generating light that is collected by an optical system that collects light leaving the light source within a predetermined acceptance angle relative to an axis defined in relation to the optical system. The light source includes a plurality of LEDs mounted on a reflecting base. Each of the LEDs generates light that leaves that LED via a top surface, a bottom surface, and one or more side surfaces of the LED. The reflecting base has a reflective surface in contact with the bottom surface of each of the LEDs. Light leaving the side surfaces of the LEDs is reflected into the acceptance angle of the optical system by a plurality of reflectors. In one embodiment of the invention, the reflectors include a plurality of reflecting facets for reflecting light leaving the side surfaces of the LEDs. The facets may be part of the reflective base or separate objects located between the LEDs. In another embodiment of the invention, the reflectors include scattering centers located between the LEDs.
