Solitons in spiraling Vogel lattices

TL;DR

This paper demonstrates that Vogel optical lattices support stable solitons with unique spiraling motion, expanding understanding of light behavior in complex, non-periodic structures in both self-focusing and defocusing media.

Contribution

It reveals the existence of stable solitons in Vogel lattices and introduces their ability to generate spiraling motion, a novel feature in such non-periodic lattices.

Findings

Stable solitons exist in Vogel lattices in both media types.

Solitons can exhibit spiraling propagation due to lattice structure.

Propagation constants form gap-like domains in the spectrum.

Abstract

We address light propagation in Vogel optical lattices and show that such lattices support a variety of stable soliton solutions in both self-focusing and self-defocusing media, whose propagation constants belong to domains resembling gaps in the spectrum of a truly periodic lattice. The azimuthally-rich structure of Vogel lattices allows generation of spiraling soliton motion.
