Research in Free-Space-Optical Visible-Spectrum Communications (Visible Light Communications)


We are investigating a systems problem -- the adaptation of novel LED-based materials and devices for the support of visible-light-based communication and communications networking. By exploiting the ubiquity of future man-made lighting from solid state (LED) devices we anticipate ubiquitous network connectivity. Our research is directed at the intersection of networking, free-space optical communications, and the "anywhere" computing that they enable. Examples include supporting "trickle" data dissemination in sensor networks, achieving HD video streaming in high bandwidth-density scenarios such as aircraft seating, and improving vehicular safety via robust vehicle-to-vehicle communications.
