US Classification:
372 39, 372 4301
Abstract:
Light sources are disclosed. A disclosed light source includes a III-V based pump light source () that includes nitrogen and emits light at a first wavelength. The light source further includes a vertical cavity surface emitting laser (VCSEL) that converts at least a portion of the first wavelength light () emitted by the pump light source () to at least a partially coherent light at a second wavelength (). The VCSEL includes first and second mirrors () that form an optical cavity for light at the second wavelength. The first mirror () is substantially reflective at the second wavelength and includes a first multilayer stack. The second mirror () is substantially transmissive at the first wavelength and partially reflective and partially transmissive and the second wavelength. The second mirror includes a second multilayer stack. The VCSEL further includes a semiconductor multilayer stack () that is disposed between the first and second mirrors and converts at least a portion of the first wavelength light to the second wavelength light.

US Classification:
257 84, 438 25, 257E33072, 257E33076
Abstract:
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 λto visible light at a second wavelength λ, 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 λ. 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.

Abstract:
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.
