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: 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
