    摘要: Systems and methods for encoding information in the topology of superpositions of helical modes of light, and retrieving information from each of the superposed modes individually or in parallel. These methods can be applied to beams of light that already carry information through other channels, such as amplitude modulation or wavelength dispersive multiplexing, enabling such beams to be multiplexed and subsequently demultiplexed. The systems and methods of the present invention increase the number of data channels carried by a factor of the number of superposed helical modes.

    摘要: A system and method for creating extended optical traps for applying optical forces to a material to be manipulated for a commercial application. The system and method include applying a hologram of appropriate characteristics to a beam of light wherein the hologram characteristics include a transverse optical component to apply optical forces transverse to an optical axis of the system. A shape phase component achieves this transverse optical component and also intensity gradient components can be applied via the hologram to provide programmable extended optical traps for a selectable commercial application.

    摘要: A method and system for providing multi-color holographic optical traps and patterns. The method and system employs a laser beam which interacts with a diffractive optical element with a hologram and for optics which acts to selectively pass or attenuate different light color wavelengths and to position the particular color light at selected different locations to form the different color holographic optical trap patterns and to use these patterns for various commercial purposes.

    摘要: 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.
