OLEDs can be used for optical communication and, working with the team of Prof Harald Haas we have just demonstrated a record communication rate of 4 Gbps over a distance of 2 m. The paper “High-speed organic light-emitting diodes based on dinaphthylperylene achieving 4-Gbps communication” shows organic optoelectronic devices can be very fast and has been published with Advanced Photonics.
