A subwavelength spot and a three-dimensional optical trap formed by a single planar element with azimuthal light
The generation of subwavelength spots smaller than the Abbe diffraction limit has attracted great interest due to the various applications in many fields, such as high-density optical data storage and particle manipulation. Planar optics that can miniaturize conventional refractive optics have becom...
