Abstract

We demonstrate experimentally new families of vector solitons with locked and precessing states of polarization for fundamental and multipulse soliton operations in a carbon nanotube mode-locked fiber laser with anomalous dispersion laser cavity.

Highlights

Polarization dynamics in lasers have been intensively studied for more than two decades in the context of various applications in fiber optic communication, fiber optic sensors, material processing and nanophotonics [1,2,3,4]

Dynamics and stability of solitons on a longer time scale is well governed by round tripbased Poincaré mapping [14] and the corresponding theory of dynamical systems leading to different “attractors” [15,16,17]

Summary

Introduction

Polarization dynamics in lasers (including gas, solid state, semiconductor, dye and fiber lasers) have been intensively studied for more than two decades in the context of various applications in fiber optic communication, fiber optic sensors, material processing (cutting, welding etc.) and nanophotonics (manipulation of asymmetric particles) [1,2,3,4] In such systems two laser modes with the same longitudinal and transverse spatial patterns and different polarization states, frequencies, and amplitudes interact through the gain sharing, phase- and amplitude selective nonlinear processes (Kerr nonlinearity) and in-cavity components (polarizers, polarization controllers etc.). Due to long cavity length and wide gain bandwidth, typically, a large number of modes are generated This leads to stochastic polarization dynamics as a result of spontaneous modelocking [9, 10]. The observed polarization attractors might be a key to the future enabling technologies of secure communications [1], trapping and manipulation of atoms and nanoparticles [2, 3] and vectorial control of magnetization [4]
