Ince-Gauss Photons in Turbulent Atmosphere: Effect of quantum numbers on beam resilience

TL;DR

This paper investigates how the quantum numbers of Ince-Gauss beams influence their robustness during propagation through turbulent atmospheres, highlighting the importance of mode parameters over basis choice.

Contribution

It provides a detailed numerical analysis of the effects of order, degree, and ellipticity on Ince-Gauss beam resilience in turbulence, a topic not extensively explored before.

Findings

Mode performance is not significantly affected by the basis choice.

Robustness depends strongly on the combination of order and degree.

Ellipticity parameters influence beam resilience in turbulence.

Abstract

In this work, we present an extensive analysis on the nature and performance of Ince-Gauss beams, elliptical solutions of the paraxial wave equation that have orbital angular momentum, as information carriers in turbulent atmosphere. We perform numerical simulations of the propagation of these beams, and focus on the effects that the order, degree and ellipticity parameters have on the robustness of the beams. We find that the choice of basis in which a mode is constructed does not greatly influence the mode performance and it is instead strongly affected by the combination of order and degree values.
