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 method for transmitting information across a water-air interface with a ultraviolet (UV) beam, the method including emitting the UV beam in a first medium, with a first optical wireless communication device; measuring a scintillation index of the UV beam in a second medium, different from the first medium, at a second optical wireless communication device; selecting, based on a value of the scintillation index, a modulation scheme for the UV beam; and modulating the UV beam with the selected modulation scheme. The UV beam has a wavelength in a range of 100 to 400 nm.

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: Example apparatuses are provided for simultaneous generation of high intensity light and modulated light signals at low modulation bias operating characteristics. An example apparatus includes a semipolar or nonpolar GaN-based substrate, a reverse-biased waveguide modulator section, and a forward-biased gain section based on InGaN/GaN quantum-well active regions, wherein the forward-biased gain section is grown on the semipolar or nonpolar GaN-based substrate. Methods of manufacturing the apparatuses described herein are also contemplated and described herein.
