Dominic O'Brien is a Professor of Engineering Science and leads the Optical Wireless Communications group. He gained MA(1991) and PhD (1993) Degrees from the Department of Engineering at the University of Cambridge. From 1993-1995 he was a NATO fellow at the Optoelectronic Computing Systems Center at the University of Colorado. His current research is in the field of optical wireless systems.
Dominic is the author or co-author of approximately 150 publications or patents in the area of optics and optoelectronics.
Dominic's interests lie in the field of optical communications. Through advances in visible light communications, he aims to gain improvements in the bandwidth and/or efficiency of a data network.
The potential for indoor free space optical communications stems from the increased uptake of solid state lighting for general illumination, due to its reliability and the potential for highly efficient sources. Compared with other sources of illumination these devices can be modulated at high data rates, offering the opportunity for communications as well as illumination from these sources.
He is also investigating the benefits of Multiple Input Multiple Output (MIMO) systems in free space optical systems, as well as the uses of optically powered 'smart dust'.
