Elimination of transverse instability in stripe solitons by one-dimensional lattices

TL;DR

This paper shows that one-dimensional photonic lattices can effectively suppress or eliminate the transverse instability of stripe solitons, both theoretically and experimentally, under self-defocusing nonlinear conditions.

Contribution

It introduces a method to control soliton stability using one-dimensional lattices in a self-defocusing nonlinear medium, combining theoretical and experimental approaches.

Findings

Transverse instability of stripe solitons can be greatly suppressed.

Complete elimination of instability achieved in experiments.

Theoretical predictions match experimental results.

Abstract

We demonstrate theoretically and experimentally that the transverse instability of coherent soliton stripes can be greatly suppressed or totally eliminated when the soliton stripes propagate in a one-dimensional photonic lattice under self-defocusing nonlinearity.
