Trapping of dark vector solitons in a fiber laser

TL;DR

This paper reports the experimental observation and numerical confirmation of incoherently coupled dark vector solitons trapped in a fiber laser, demonstrating their synchronous trapping despite differences in frequency, energy, and darkness.

Contribution

It presents the first experimental observation of incoherently coupled dark vector soliton trapping in a fiber laser, supported by numerical simulations confirming the phenomenon.

Findings

Dark vector solitons can be synchronously trapped in a fiber laser.

Incoherent interactions enable trapping despite differences in polarization and frequency.

Numerical simulations match experimental results confirming the existence of these solitons.

Abstract

We report on the experimental observation of incoherently coupled dark vector soliton trapping in a fiber laser. Dark vector solitons along the two orthogonal polarization directions though with large difference in central frequency, energy and darkness could be still synchronously trapped as a group velocity locked dark vector soliton in virtue of the incoherent interactions. Our numerical simulation could well rebirth the experimental observations and confirm the existence of incoherently coupled dark vector soliton under certain conditions.
