TL;DR
This paper experimentally investigates how spatial optical solitons, called nematicons, propagate and interact in a bias-free nematic liquid crystal cell, revealing boundary effects and the influence of initial conditions.
Contribution
It provides new experimental insights into nematicon interactions and boundary effects in bias-free liquid crystal cells, which were not thoroughly explored before.
Findings
Long-range boundary effects on nematicon propagation
Interaction dynamics of in-phase and out-of-phase nematicons
Influence of initial beam focusing and input angle on interactions
Abstract
We study experimentally the propagation dynamics and interaction of spatial optical solitons in a bias-free cell filled with nematic liquid crystals. We reveal and measure long-range effects due to the cell boundaries for a single nematicon as well as for the interacting in-phase and out-of-phase nematicons. We discuss the effect of initial beam focusing and relative input angle on the interaction of in-phase nematicons.
