摘要： Light emitting systems are disclosed. The light emitting system includes an LED that emits light at a first wave-length. A primary portion of the emitted first wavelength light exits the LED from a top surface of the LED that has a minimum lateral dimension Wmin. The remaining portion of the emitted first wavelength light exits the LED from one or more sides of the LED that has a maximum edge thickness Tmax (122, 124). The ratio Wmin/Tmax is at least 30. The light emitting system further includes a re-emitting semiconductor construction that includes a semiconductor potential well. The re-emitting semiconductor construction receives the first wavelength light that exits the LED from the top surface and converts at least a portion of the received light to light of a second wavelength. The integrated emission intensity of all light at the second wavelength that exit the light emitting system is at least 4 times the integrated emission intensity of all light at the first wavelength that exit the light emitting system.

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.
