    摘要: Optical devices and methods of manufacturing and operating such optical devices. In an embodiment, an optical device includes a substrate, a multi-layer structure having a first surface in contact with a first surface of the substrate, a first mirror disposed over a second surface of the multi-layer structure, a second mirror disposed over a second surface of the substrate, an intermediate mirror within the multi-layer structure, and an optical gain structure within the multi-layer structure. The device may include a first optically resonant cavity within the multi-layer structure, bounded by the first mirror and the intermediate mirror, where the first optically resonant cavity includes the optical gain structure. The device may further include a second optically resonant cavity, bounded by the first and second mirrors, where the second optically resonant cavity includes the first optically resonant cavity, the second optically reflective layer, and the substrate.

    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 high efficiency light emitting diode (LED) comprised of a substrate, a buffer layer grown on the substrate (if such a layer is needed), a first active region comprising primary emitting species (PES) that are electrically-injected, a second active region comprising secondary emitting species (SES) that are optically-pumped by the light emitted from the PES, and photonic crystals, wherein the photonic crystals act as diffraction gratings to provide high light extraction efficiency, to provide efficient excitation of the SES, and/or to modulate the far-field emission pattern.

    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.
