    摘要: An arrangement of light sources is attached to a semiconductor wavelength converter. Each light source emits light at a respective peak wavelength, and the arrangement of light sources is characterized by a first range of peak wavelengths. The semiconductor wavelength converter is characterized by a second range of peak wavelengths when pumped by the arrangement of light sources. The second range of peak wavelengths is narrower than the first range of peak wavelengths. The semiconductor wavelength converter is characterized by an absorption edge having a wavelength longer than the longest peak wavelength of the light sources. The wavelength converter may also be used for reducing the wavelength variation in the output from an extended light source.

    摘要: Re-emitting semiconductor constructions (RSCs) for use with LEDs, and related devices, systems, and methods are disclosed. A method of fabrication includes providing a semiconductor substrate, forming on a first side of the substrate a semiconductor layer stack, attaching a carrier window to the stack, and removing the substrate after the attaching step. The stack includes an active region adapted to convert light at a first wavelength λ1 to visible light at a second wavelength λ2, the active region including at least a first potential well. The attaching step is carried out such that the stack is disposed between the substrate and the carrier window, which is transparent to the second wavelength λ2. The carrier window may also have a lateral dimension greater than that of the stack. The removal step is carried out so as to provide an RSC carrier device that includes the carrier window and the stack.

    摘要: A light emitting diode (LED) has various LED layers provided on a substrate. A multilayer semiconductor wavelength converter, capable of converting the wavelength of light generated in the LED to light at a longer wavelength, is attached to the upper surface of the LED by a bonding layer. One or more textured surfaces within the LED are used to enhance the efficiency at which light is transported from the LED to the wavelength converter. In some embodiments, one or more surfaces of the wavelength converter is provided with a textured surface to enhance the extraction efficiency of the long wavelength light generated within the converter.
