Analysis of Confinement in Dual Spherical-Tapered Ended Fiber Optical Trap
Applied Sciences, 2022 In dual-fiber optical traps, two counter-propagating laser beams emitted from opposing laser fibers trap and manipulate particles. We describe the operation and performance of a dual-fiber optical trap created using spherical-tapered ended fiber ...

Accounting for polarization in the calibration of a donut beam axial optical tweezers. [PDF]
PLoS ONE, 2018 Advances in light shaping techniques are leading to new tools for optical trapping and micromanipulation. For example, optical tweezers made from Laguerre-Gaussian or donut beams display an increased axial trap strength and can impart angular momentum to

Efficient generation of optical bottle beams
Nanophotonics, 2021 Optical bottle beams can be used to trap atoms and small low-index particles. We introduce a figure of merit (FoM) for optical bottle beams, specifically in the context of optical traps, and use it to compare optical bottle-beam traps obtained by three ...
