In depth fiber optic trapping of low-index microscopic objects
K. S. Mohanty, C. Liberale, S. K. Mohanty, and V. Degiorgio
We demonstrate that a focused beam through a microaxicon built on the tip of a single mode optical fiber can trap low-index objects at much larger depths as compared to the vortex beam tweezers generated using high numerical aperture microscope objectives. The measured transverse trapping force for ... [Appl. Phys. Lett. 92, 151113 (2008)] published Fri Apr 18, 2008.
