Abstract: A dislocation-free GaN/InGaN-based nanowires-LED epitaxially grown on a transparent, electrically conductive template substrate. The simultaneous transparency and conductivity are provided by a thin, translucent metal contact integrated with a quartz substrate. The light transmission properties of the translucent metal contact are tunable during epitaxial growth of the nanowires LED. Transparent light emitting diodes (LED) devices, optical circuits, solar cells, touch screen displays, and integrated photonic circuits can be implemented using the current platform.

Abstract: Gallium nitride based semiconductors are provided having one or more passivated surfaces. The surfaces can have a plurality of thiol compounds attached thereto for enhancement of optoelectronic properties and/or solar water splitting properties. The surfaces can also include wherein the surface has been treated with chemical solution for native oxide removal and/or wherein the surface has attached thereto a plurality of nitrides, oxides, insulating compounds, thiol compounds, or a combination thereof to create a treated surface for enhancement of optoelectronic properties and/or solar water splitting properties. Methods of making the gallium nitride based semiconductors are also provided. Methods can include cleaning a native surface of a gallium nitride semiconductor to produce a cleaned surface, etching the cleaned surface to remove oxide layers on the surface, and applying single or multiple coatings of nitrides, oxides, insulating compounds, thiol compounds, or a combination thereof attached to the surface.

Abstract: A method of forming an optoelectronic semiconductor device involves providing an amorphous substrate. A transparent and conductive oxide layer is deposited on the amorphous substrate. The transparent and conductive oxide layer is annealed to form an annealed transparent and conductive oxide layer having a cubic-oriented and/or rhombohedral-oriented surface. A nanorod array is formed on the cubic-oriented and/or rhombohedral-oriented surface of the annealed transparent and conductive oxide layer. The annealing of the transparent conductive oxide layer and the formation of the nanorod array are performed using molecular beam epitaxy (MBE). The nanorods of the nanorod array comprise a group-III material and are non-polar.

Abstract: Embodiments of the present disclosure describe an underwater optical communication and illumination system employing laser diodes directly encoded with data, including spectrally efficient orthogonal frequency division multiplex quadrature amplitude modulation (QAM-OFDM) data. A broadband light source may be utilized to provide both illumination to an underwater field of interest and underwater optical communication from the field of interest to a remote location.

Abstract: A visible-light communication and illumination array includes a substrate and plural surface-emitting superluminescent diodes, SLDs, distributed across the substrate. A first set of SLDs of the plural SLDs generates a first light beam having substantially a first wavelength, a second set of SLDs of the plural SLDs generates a second light beam having substantially a second wavelength, and a third set of SLDs of the plural SLDs generates a third light beam having substantially a third wavelength. The array further includes a controller configured to encode at least one of the first light beam, the second light beam and the third light beam to transmit information. A combination of the first light beam, the second light beam and the third light beam produces white light.

Abstract: Embodiments of the present disclosure describe a white light illumination system using InGaN-based orange nanowires (NWs) LED, in conjunction with a blue LD for high speed optical wireless communications. By changing the relative intensities of an ultrabroad linewidth orange LED and narrow-linewidth blue LD components, a hybrid LED/LD device achieves correlated color temperature (CCT) ranging from 3000 K to above 6000K with color rendering index (CRI) values reaching 83.1. Orange-emitting NWs LED are utilized as an active-phosphor, while a blue LD was used for both color mixing and optical wireless communications

Abstract: An optical mirror diversity receiver for a visible light communication system is provided with an array of photodiodes each having an optical-signal-receiving area, with a mirror positioned between an adjacent pair of photodiodes to preferentially redirect light toward one of the photodiodes while also blocking light that would otherwise be received at the photodiode. An angle-aided mirror diversity receiver is also provided with surfaces of the photodiodes aligned relative to the mirror to yield reductions in correlation.
