Breaking the symmetric spiral spectrum distribution of a Laguerre-Gaussian beam propagating in moderate-to-strong isotropic atmospheric turbulence

D Wu, H Wang, F Wang, G Wu, X Zhu, Y Cai - Optics Express, 2024 - opg.optica.org
We demonstrate that the spiral spectrum (also known as orbital angular momentum
spectrum) of a Laguerre-Gaussian (LG) beam with topological charge (TC) l is …

Performance of Orbital Angular Momentum Communication for a Non-Uniformly Correlated High-Order Bessel–Gaussian Beam in a Turbulent Atmosphere

Z Cong, H Zhang, Y Gao, Y Cai, Y Yuan - Photonics, 2024 - mdpi.com
We derived the formula for the detection probability, signal-to-noise ratio (SNR), and
average bit error rate (BER) for the signal orbital angular momentum (OAM) state carried via …
