All-inorganic halide-perovskite-polymer luminescent fibers for high-bitrate ultraviolet free-space optical communication

We demonstrate, for the first time, halide-perovskite-polymer-based luminescent fibers as a high-bitrate and near-omnidirectional photodetection platform for 375-nm ultraviolet laser-based free-space optical communication. Our demonstrations could enable future ultraviolet-to-visible optical receivers based on all-inorganic halide-perovskite nanomaterial to cater various dynamic scenarios in optical wireless communication.
