Ultra-thin plasmonic optical vortex plate based on phase discontinuities Academic Article uri icon

abstract

  • A flat optical device that generates optical vortices with a variety of topological charges is demonstrated. This device spatially modulates light beams over a distance much smaller than the wavelength in the direction of propagation by means of an array of V-shaped plasmonic antennas with sub-wavelength separation. Optical vortices are shown to develop after a sub-wavelength propagation distance from the array, a feature that has major potential implications for integrated optics. © 2012 American Institute of Physics.
