Generation and characterization of customized perfect Laguerre-Gaussian beams with arbitrary profiles
Chengyuan Wang, Yun Chen, Jinwen Wang +3
We experimentally demonstrate the generation of customized perfect Laguerre-Gaussian (PLG) beams whose intensity maxima localized around any desired curves. The principle is to act…
Arbitrary cylindrical vector beam generation enabled by polarization-selective Gouy phase shifter
J. Jia, K. Zhang, G. Hu +7
Cylindrical vector beams (CVBs), which possesses polarization distribution of rotational symmetry on the transverse plane, can be developed in many optical technologies. Convention…
Type-II Dirac photonic lattices
Kaichao Jin, Hua Zhong, Yongdong Li +5
Different from the Fermi surface of the type-I Dirac semimetal being a point, that of the type-II Dirac semimetal is a pair of crossing lines because the Dirac cone is tilted with…
Rabi-like oscillation of photonic topological valley Hall edge states
Hua Zhong, Yaroslav V. Kartashov, Yiqi Zhang +4
We investigate Rabi-like oscillations of topological valley Hall edge states by introducing two zigzag domain walls in an inversion-symmetry-breaking honeycomb photonic lattice. Su…
Enhancement of spatial resolution of ghost imaging via localizing and thresholding
Yunlong Wang, Yingnan Zhou, Shaoxiong Wang +5
In ghost imaging scheme, an illuminated light is split into test and reference beams which pass through two different optical systems respectively and an image is constructed by th…
An experimental measurement of the topological charge of orbital angular momentum beams through weak measurement
Jing Zhu, Pei Zhang, Qichang Li +7
As a special experimental technique, weak measurement extracts very little information about the measured system and will not cause the measured state collapse. When coupling the o…
