  • Extended and knotted optical traps in three dimensions
    Patent number: 8921763
    Abstract: The present invention is directed toward a system and method for projecting holographic optical traps whose intensity maxima are extended along specified paths in three dimensions with specified amplitude and phase profiles along those paths. Specifying paths that constitute knotted loops and phase profiles that direct radiation pressure along the knotted paths yields optical traps that exert knotted force fields. Knotted optical force fields have uses for inducing motion along knotted paths, with applications including the generation of knotted electric current loops in plasmas.
    Type: Grant
