Multi-modes Bessel-Gaussian-Orbital Angular Momentum Beams Quantum Holography
Jinjin Li, Chaoying Zhao
We propose an orbital angular momentum (OAM) quantum holography scheme based on multi-mode Bessel-Gaussian (MBG) beams. Entangled photon pairs are generated through spontaneous par…

The multi-modes Bessel-Gaussian OAM hologram encoding based on convolutional neural networks
Jinjin Li, Chaoying Zhao
Multi-mode vortex light is a superposition of different orbital angular momentum (OAM) lights. However, as the number of OAM modes increases, the sampling constant changes. Using t…

A broadband vortex beam generation by reflective meta-surface based on metal double-slit resonant ring
Xufeng Yuan, Chaoying Zhao
Recently, meta-surface(MS) has emerged as a promising alternative method for generating vortex waves. At the same time, MS also face the problem of narrow bandwidth, in order to ob…
