Far-field radially polarized focal spot from plasmonic spiral structure combined with central aperture antenna
Manipulation of a vector micro-beam with an optical antenna has significant potentials for nano-optical technology applications including bio-optics, optical fabrication, and quantum information processing. We have designed and demonstrated a central aperture antenna within an Archimedean spiral tha...
