Light beam carrying natural non-integer orbital angular momentum in free space
Xiaoyu Weng, Yu Miao, Guanxue Wang +5
Light beam with optical vortices can propagate in free space only with integer orbital angular momentum. Here, we invert this scientific consensus theoretically and experimentally…

THz Near-Field Imaging of Extreme Subwavelength Metal Structures
Xinzhong Chen, Xiao Liu, Xiangdong Guo +15
Modern scattering-type scanning near-field optical microscopy (s-SNOM) has become an indispensable tool in material research. However, as the s-SNOM technique marches into the far-…

Extraction of inherent polarization modes from a single light beam
Xiaoyu Weng, Yu Miao, Qingli Zhang +4
Superposition of two independent orthogonally polarized beams is a conventional principle of creating a new light beam. Here, we intend to achieve the inverse process, namely, extr…
