Precise position- and angular-controllable optical trapping and manipulation via a single vortex-pair beam
Jisen Wen, Binjie Gao, Dadong Liu +2
Optical trapping and manipulation using laser beams play a key role in many areas including biology, atomic science, and nanofabrication. Here, we propose and experimentally demons…

Observation of multiramp fractional vortex beams and their properties in free space
Jisen Wen, Binjie Gao, Guiyuan Zhu +3
We have experimentally investigated the evolution properties of multiramp fractional vortex beams (MFVBs) in free space, by using a fundamental Gaussian beam reflecting from a phas…

On vortex strength and beam propagation factor of fractional vortex beams
Jisen Wen, Li-Gang Wang, Xihua Yang +2
Fractional vortex beams (FVBs) with non-integer topological charges attract much attention due to unique features of propagations, but there still exist different viewpoints on the…
