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
