We report on the experimental demonstration of super-resolved pure-transverse focal fields through focusing an azimuthally polarized first-order vortex (FOV) beam. The optimized confinement of focal fields by creating constructive interference through the superposition of the FOV on an azimuthally polarized beam is observed by both a scanning near-field… CONTINUE READING
