Abstract

We demonstrate a far-UVC optical wireless communication system employing µLED transmitters emitting at 235 nm. Reducing the device dimensions to the micro-metre regime decreases the active area, enabling higher current densities and lower junction capacitance, which together enhance the modulation bandwidth relative to conventional large-area AlGaN LEDs. The resulting improvement in high-speed performance allows the intrinsic bandwidth limitations of deep-ultraviolet emitters to be mitigated. Using these µLEDs in a short-range free-space link, data rates of up to 1.5 Gbps are achieved. These results highlight the potential of far-UVC µLED technology for compact, solar-blind optical wireless communication systems requiring high data throughput.
