Topologically protected generation of spatiotemporal optical vortices with nonlocal spatial-mirror-symmetry-breaking metasurface
Junyi Huang, Hongliang Zhang, Tengfeng Zhu +1
Recently nonlocal spatial-mirror-symmetry-breaking metasurfaces have been proposed to generate spatiotemporal optical vortices (STOVs), which carry transverse orbital angular momen…
Spatiotemporal differentiators generating optical vortices with transverse orbital angular momentum and detecting sharp change of pulse envelope
Junyi Huang, Jiahao Zhang, Tengfeng Zhu +1
As a new degree of freedom for optical manipulation, recently spatiotemporal optical vortices (STOVs) carrying transverse orbital angular momentums have been experimentally demonst…
Optical phase mining by adjustable spatial differentiator
Tengfeng Zhu, Junyi Huang, Zhichao Ruan
Phase is a fundamental resource for optical imaging but cannot be directly observed with intensity measurements. The existing methods to quantify a phase distribution rely on compl…
Generalized spatial differentiation from spin Hall effect of light
Tengfeng Zhu, Yijie Lou, Yihan Zhou +9
Optics naturally provides us with some powerful mathematical operations. Here we experimentally demonstrate that during reflection or refraction at a single optical planar interfac…
