Walking vector soliton caging and releasing

TL;DR

This paper investigates the formation, stability, and controlled release of vector solitons in optical lattices, highlighting how lattice parameters influence soliton trapping and movement in anisotropic media.

Contribution

It introduces a mechanism for caging and releasing vector solitons in optical lattices, considering anisotropy-induced walk-off effects, and demonstrates control over soliton dynamics.

Findings

Stable vector solitons form above a power threshold

Reducing lattice depth releases trapped solitons

Releasing solitons allows controlled movement across the lattice

Abstract

We address the formation and propagation of vector solitons in optical lattices in the presence of anisotropy-induced walk-off between ordinary and extraordinary polarized field components. Stable vector solitons trapped by the lattice form above a threshold power, while decreasing the lattice depth below a critical value results in the abrupt release of the caged solitons, that then move across the lattice and may get trapped in a desired lattice channel.
