    Abstract: A THz quantum cascade laser is used to investigate a target by directing a first beam of laser radiation from the laser at the target to thereby produce a second beam of laser radiation by interaction of the first beam with the target. Self-mixing of the first and second beams occurs within the laser and causes variations in a signal such as the operating voltage of the laser. An operating parameter of the laser that affects the interaction of the first beam with, the target is varied. The operating voltage is monitored and processed to determine phase and amplitude changes associated with material properties of the target. Consequently in one embodiment the invention provides for processing the variations in the signal to produce various images of the target.

  • Patent number: 9799809
    Abstract: A light-emitting diode (LED) package includes a light-emitting structure, an optical wavelength conversion layer on the light-emitting structure, and an optical filter layer on the optical wavelength conversion layer. The light-emitting structure includes a first-conductivity-type semiconductor layer, an active layer on the first-conductivity-type semiconductor layer, and a second-conductivity-type semiconductor layer on the active layer, and emits first light having a first peak wavelength. The optical wavelength conversion layer absorbs the first light emitted from the light-emitting structure and emits second light having a second peak wavelength different from the first peak wavelength. The optical filter layer reflects the first light emitted from the light-emitting structure and transmits the second light emitted from the optical wavelength conversion layer.

  • Patent number: 9599292
    Abstract: A light emitting module includes at least one LED mounted on a reflective base and surrounded by reflective walls to form a cavity. A partially diffusive layer containing a phosphor is mounted above the LED with a gap therebetween. Some of the light emitted by the phosphor is backscattered toward the LED, base, and walls. The LED absorbs a significant amount of the light, while the reflective base and walls efficiently reflect over 90% of the light back toward the phosphor layer for exiting the module. Various equations are provided that allow the designer to select an optimal gap between the LED and the partially diffusive layer to maximize light extraction efficiency out of the diffusive layer. The optimal gap range for maximizing light extraction efficiency is a product of LED largest linear length, LED surface area, base area, wall area, and reflective coefficients of the various elements.

  • Patent number: 9559272
    Abstract: Broadband solid state light sources include remote phosphor LED(s), short-wavelength direct emitting LED(s), and long-wavelength direct emitting LED(s). A diffuse or clear cover member covers these LEDs. Each remote phosphor LED includes an LED, a phosphor layer, and a dichroic reflector. The light sources can provide a broadband output light over a wide color range, and can do so efficiently while energizing a high percentage or proportion of the total number of LEDs in the system. The broadband output may for example exhibit a color difference of at least 0.2 in CIE chromaticity units, and/or a correlated color temperature difference of at least 4000 or 5000 Kelvin, while energizing more than half, or at least 60%, or at least 70%, of the total number of LEDs. Numbers of LEDs can be replaced with effective numbers of LEDs if LEDs of substantially different sizes are included in the light source.
