TL;DR

This paper reports the experimental observation and numerical confirmation of dispersion-managed dark solitons in a net-normal dispersion erbium-doped fiber laser, highlighting reduced pump thresholds and stabilized soliton evolution.

Contribution

It demonstrates for the first time that dispersion management can reduce the threshold and stabilize dark solitons in fiber lasers.

Findings

Dispersion management reduces the pump threshold for dark soliton formation.

DM dark solitons are stabilized in the fiber laser cavity.

Numerical simulations confirm experimental observations.

Abstract

We report on the observation of dispersion-managed (DM) dark soliton emission in a net-normal dispersion erbium-doped fiber laser. We found experimentally that dispersion management could not only reduce the pump threshold for the dark soliton formation in a fiber laser, but also stabilize the single dark soliton evolution in the cavity. Numerical simulations have also confirmed the DM dark soliton formation in a fiber laser.
