20150288129 | Optically Surface-Pumped Edge-Emitting Devices and Systems and Methods of Making Same - Optical resonator devices and systems enhanced with photoluminescent phosphors and designed and configured to output working light in an edge-emitting fashion at one or more wavelengths based on input/pump light, and systems and devices made with such resonators. The edge-emitting functionality is enabled by providing one or more waveguides that direct light luminesced from the phosphors to one or more edges of the device. In some embodiments, the resonators contain multiple optical resonator cavities in combination with one or more photoluminescent phosphor layers or other structures. In other embodiments, the resonators are designed to simultaneously resonate at the input/pump and output wavelengths. The photoluminescent phosphors can be any suitable photoluminescent material, including semiconductor and other materials in quantum-confining structures, such as quantum wells and quantum dots, among others. | 10-08-2015 |
20140367719 | Phosphors For Use With LEDS and Other Optoelectronic Devices - Phosphors fabricated from one or more layers of a naturally lamellar or fabricated lamellar semiconductor that is combined with a substrate. One or more of the layers of the lamellar semiconductor are separated from bulk material. The one or more layers are transformed into a phosphor for use with one or more light-emitting devices for the purpose of modifying the light emitted by the light-emitting device(s). Such transformation can be effected in a variety of ways, such as precise thinning or thickening of the removed layer(s) and/or intercalating one or more species of ions into the layer(s) that function as phosphors. | 12-18-2014 |

20140024159 | Optoelectronic Device Containing at Least One Active Device Layer Having a Wurtzite Crystal Structure, and Methods of Making Same - Optoelectronic devices, such as light-emitting diodes, laser diodes, image sensors, optical detectors, etc., made by depositing (growing) one or more epitaxial semiconductor layers on a monocrystalline lamellar/layered substrate so that each layer has a wurtzite crystal structure. In some embodiments, the layers are deposited and then one or more lamellas of the starting substrate are removed from the rest of the substrate. In one subset of such embodiments, the removed lamella(s) is/are partially or entirely removed. In other embodiments, one or more lamellas of the starting substrate are removed prior to depositing the one or more wurtzite-crystal-structure-containing layer(s). | 01-23-2014 |
20130143336 | Methods of Fabricating Optoelectronic Devices Using Layers Detached from Semiconductor Donors and Devices Made Thereby - Methods of making optoelectronic devices containing functional elements made from layers liberated from natural and/or fabricated lamellar semiconductor donors. In one embodiment, a donor is provided, a layer is detached from the donor, and the layer is incorporated into an optoelectronic device as a functional element thereof. The thickness of the detached layer is tuned as needed to suit the functionality of the functional element. Examples of functional elements that can be made using detached layers include p-n junctions, Schotkey junctions, PIN junctions, and confinement layers, among others. Examples of optoelectronic devices that can incorporate detached layers include LEDs, laser diodes, MOSFET transistors, and MISFET transistors, among others. | 06-06-2013 |
