    摘要: A single or multi-color light emitting diode (LED) with high extraction efficiency is comprised of a substrate, a buffer layer formed on the substrate, one or more patterned layers deposited on top of the buffer layer, and one or more active layers formed on or between the patterned layers, for example by Lateral Epitaxial Overgrowth (LEO), and including one or more light emitting species, such as quantum wells. The patterned layers include a patterned, perforated or pierced mask made of insulating, semiconducting or metallic material, and materials filling holes in the mask. The patterned layer acts as an optical confining layer due to a contrast of a refractive index with the active layer and/or as a buried diffraction grating due to variation of a refractive index between the mask and the material filling the holes in the mask.

    摘要: A structure using integrated optical elements is comprised of a substrate, a buffer layer grown on the substrate, one or more patterned layers formed on the buffer layer and one or more active layers formed on or between the patterned layers, for instance by Lateral Epitaxial Overgrowth (LEO), and including one or more light emitting species. The patterned layer comprises a mask (made of insulating, semiconducting or metallic material) and material filling holes in the mask. The patterned layer, due to a large index difference with the active layer and/or variations of a refractive index between the mask and materials filling holes in the mask, acts as an optical confinement layer, a mirror, a diffraction grating, a wavelength selective element, a beam shaping element or a beam directing element.

    摘要: A white, single or multi-color light emitting diode (LED) includes a mirror for reflecting photons within the LED; a first active region, adjacent the mirror, including one or more current-injected layers for emitting photons when electrically biased in a forward direction; a second active region, adjacent the first active region, including one or more optically-pumped layers for emitting photons, wherein the optically-pumped layers are optically excited by the photons emitted by the current-injected layers, thereby recycling guided modes; and an output interface, adjacent the second active region, for allowing the photons emitted by the optically-pumped layers to escape the LED as emitted light.
