TL;DR: A hybrid Si-based photodetection scheme by incorporating CsPbBr3 perovskite nanocrystals (NCs) with a high photoluminescence quantum yield (PLQY) and a fast photolity decay time as a UV-to-visible colour-converting layer for high-speed solar-blind UV communication is reported.

TL;DR: This work was partially supported by the King Abdullah University of Science and Technology (KAUST) baseline funding, as well as KAUST-KFUPM Special Initiative (KKI) Program, REP/1/2878-01-01.

TL;DR: This work investigates the thin-film growth of a heterostructure stack comprised of n-type β-Ga2O3 and p-type cubic NiO layers grown consecutively on c-plane sapphire using pulsed laser deposition, as well as the fabrication of solar-blind ultraviolet-C photodetectors based on the resulting p-n junction heterodiodes.

TL;DR: Novel solutions are proposed to ease the requirements on pointing, acquisition, and tracking (PAT) for establishing robustness in UWOC links, which include light-scattering-based non-line-of-sight (NLOS) communication modality as well as PAT-relieving scintillating-fiber-based photoreceiver and large-photovoltaic cells as the optical signal detectors.

TL;DR: A large-area, high bandwidth, and wide-angle-of-view photoreceiver design based on ultraviolet(UV)-to-blue color-converting plastic scintillating fibers, and yet offering high 3-dB bandwidth of up to 86.13 MHz is demonstrated, opening the pathway for revolutionizing the photodetection scheme in UWOC, and for non-line- of-sight (NLOS) free-space optical communication.
