Multi-mode fiber enabled multi-wavelength optical trapping and dynamic manipulation
Yikun Shen, Chuangye Zhang, Yuquan Zhang +7
The paper presents an optical tweezer system that uses a multi‑mode fiber equipped with a micro‑lens to achieve stable, multi‑wavelength trapping and dynamic manipulation of cells…
Ultrafast wide-field 3D topography with extended depth of field
Qianyi Wei, Jielei Ni, Yuquan Zhang +6
Ultrafast optical imaging has enabled direct observation of femtosecond-nanosecond dynamics, yet three-dimensional (3D) dynamic measurements at high numerical aperture (NA) remain…
Temporal Focusing Enables Distortion-Resistant high-intensity Spatiotemporal Optical Vortices
Jielei Ni, Yao Zhang, Qianyi Wei +10
Spatiotemporal optical vortices (STOVs) carry transverse orbital angular momentum and offer new degrees of freedom for light-matter interactions. Yet conventional focusing of STOVs…
Controllable perfect spatiotemporal optical vortices
Shuoshuo Zhang, Zhangyu Zhou, Zhongsheng Man +4
Spatiotemporal optical vortices (STOVs), as a kind of structured light pulses carrying transverse orbital angular momentum (OAM), have recently attracted significant research inter…
