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…
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…
Spatial sub-Rayleigh imaging analysis via speckle laser illumination
Yunlong Wang, Feiran Wang, Ruifeng Liu +4
It is commonly accepted that optical sub-Rayleigh imaging has potential application in many fields. In this Letter, by confining the divergence of the optical field, as well as the…
Measuring mode indices of a partially coherent vortex beam with HBT type experiment
Ruifeng Liu, Feiran Wang, Dongxu Chen +5
It is known that the cross-correlation function (CCF) of a partially coherent vortex (PCV) beam shows a robust link with the radial and azimuthal mode indices. However, the previou…

Dongzhi Fu, Dongxu Chen, Ruifeng Liu +4
When a vortex beam with the spiral phase structure passes through a dynamic angular double slits (ADS), the interference pattern changes alternatively between destructive and const…
Two-photon interference with two independent and tunable single-mode continuous-wave lasers
Jianbin Liu, Dong Wei, Hui Chen +5
The second-order temporal interference between two independent single-mode continuous-wave lasers is discussed by employing two-photon interference in Feynman's path integral theor…
