摘要： A stack of semiconductor layers (310) forms a re-emitting semiconductor construction (RSC). The stack (310) includes an active region (316) that converts light at a first wavelength to light at a second wavelength, the active region (316) including at least one potential well. The stack (310) also includes an inactive region (318) extending from an outer surface of the stack to the active region. Depressions (326) are formed in the stack (310) that extend from the outer surface into the inactive region (318). An average depression depth is at least 50% of a thickness of the inactive region. Alternatively, the average depression depth is at least 50% of a nearest potential well distance. Still other alternative characterizations of the depressions (326) are also disclosed. The depressions (326) may have at least a 40% packing density in plan view. The depressions (326) may also have a substantial portion of their projected surface area associated with obliquely inclined surfaces.

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： 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： Light emitting systems are disclosed. The light emitting system emits an output light that has a first color. The light emitting system includes a first electroluminescent device that emits light at a first wavelength in response to a first signal. The first wavelength is substantially independent of the first signal. The intensity of the emitted first wavelength light is substantially proportional to the first signal. The light emitting system further includes a first luminescent element that includes a second electroluminescent device and a first light converting layer. The second electroluminescent device emits light at a second wavelength in response to a second signal. The first light converting layer includes a semiconductor potential well and converts at least a portion of light at the second wavelength to light at a third wavelength that is longer than the second wavelength. The light emitting system combines light at the first wavelength with light at the third wavelength to form the output light at the first color. When one of the first and second signals changes from about 50% of a maximum rating of the signal to about 100% of the maximum rating, but the ratio of the first signal to the second signal remains substantially unchanged, the first color of the output light remains substantially unchanged.

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.

摘要： An optical sensing system and method of using it includes a light source and a first bus waveguide having an input port that is in optical communication with the light source. The system further includes a microresonator configured so that the light source excites at least first and second resonant guided optical modes of the microresonator. The microresonator includes a first location on a surface of a core of the microresonator where a field intensity of the first mode is greater than a field intensity of the second mode. The microresonator core has a first cladding at the first location. The microresonator also has a second location on a surface of the core of the microresonator where a field intensity of the first mode is less than or equal to a field intensity of the second mode, the microresonator core having a second cladding at the second location. The first cladding is different than the second cladding.
