Optical storage of Ince-Gaussian modes in warm atomic vapor

Opt Lett. 2021 Mar 1;46(5):1021-1024. doi: 10.1364/OL.414762.

Abstract

We report on the optical storage of Ince-Gaussian modes in a warm rubidium vapor cell based on electromagnetically induced transparency protocol, and we also qualitatively analyze how atomic diffusion affects the retrieved beams after storage. Ince-Gaussian modes possess very complex and abundant spatial structures and form a complete infinite-dimensional Hilbert space. Successfully storing such modes could open up possibilities for fundamental high-dimensional optical communication experiments.
