Proceedings Paper

Novel micro-LED devices for visible and ultraviolet wireless optical communications (Conference Presentation)
Author(s): Martin D. Dawson

Paper Abstract

Micro-LEDs based on gallium nitride semiconductors are the basis of new formats of high-brightness, fast response and high resolution display technology, but are also very promising for applications in optical wireless communications across a broad spectral range. Indeed, micro-LED technology offers exciting prospects for convergence between these two hitherto largely separate areas of application. Here, we report on recent developments in micro-LEDs for high-bandwidth optical wireless communications, including new formats of device such as series-driven multi-pixel structures, and new wavelength devices such as those operating in the deep ultraviolet. Highlights include 10Gbps data rates over distances beyond 5m and data rates of over 1Gb/s at 20m using blue series-driven devices, underwater optical communications link demonstrations, few-photon per bit (single photon counting) operation over 10's km distances for space-based applications, and 1Gb/s operation at a wavelength of 262nm
