Super sub-wavelength patterns in photon coincidence detection
Ruifeng Liu, Pei Zhang, Yu Zhou +2
High-precision measurements implemented by means of light is desired in all fields of science. However, light is a wave and Rayleigh criterion gives us a diffraction limitation in…

Evaluating Laguerre-Gaussian beams with an invariant parameter
Junling Long, Ruifeng Liu, Yunlong Wang +4
We define a new parameter about Laguerre-Gaussian (LG) beams, named , which is only related to mode indices and . This parameter is able to both evaluate and dist…

Characterizing vortex beam with angular-double-slit interference
Ruifeng Liu, Junling Long, Feiran Wang +4
The Fraunhofer diffraction intensity distribution of Laguerre-Gaussian beam is studied in an angular-double-slit interferometer. We demonstrate that the spiral phase structure of v…
