Focusing Properties

We investigated the focusing properties of a double-ring-shaped azimuthally polarized beam tightly focused with a high NA lens and a binary phase filter. We observe that by using 3 belts and 5 belts binary phase filters novel focal patterns including splitting of focal rings and multiring focus are obtained. We also found that a suitably designed phase structure can shift the focal rings along optical axis. The author expects such investigation is worthwhile for optical manipulation and material processing technologies.

Super Resolution Microscopy

We generated a super-resolution optical tube by tightly focusing a binary phase modulated azimuthally polarized laser beam. The binary phase modulation is achieved by a glass substrate with multi-belt concentric ring grooves. We also characterized the 3D beam profile by using a cross-shaped knife-edge fabricated on a silicon photo-detector. The size of the super-resolution dark spot in the tube is 0.32[Formula: see text], which remains unchanged for [Formula: see text] within the tube. This optical tube may find applications in super-resolution microscopy, optical trapping and particle acceleration.
