Breather molecular complexes in a passively mode-locked fibre laser
Junsong Peng, Zihan Zhao, Sonia Boscolo +4
Breathing solitons are nonlinear waves in which the energy concentrates in a localized and oscillatory fashion. Similarly to stationary solitons, breathers in dissipative systems c…
Nonlinear transition between PT-symmetric and PT-broken modes in coupled fiber lasers
Sergey V. Suchkov, Dmitry V. Churkin, Andrey A. Sukhorukov
We present a systematic analysis of the stationary regimes of nonlinear parity-time(PT) symmetric laser composed of two coupled fiber cavities. We find that power-dependent nonline…
Temporal variation of the spectrum of continuously-pumped random fiber laser. Phenomenological model
Y. Bliokh, E. I. Chaikina, I. D. Vatnik +1
A temporal variation of a spectrum of excited modes in a continuously pumped erbium-doped random fiber laser (RFL), based on randomly distributed Bragg gratings, is studied. Develo…
Observation of localized modes at effective gauge field interface in synthetic photonic lattice
Artem V. Pankov, Ilya D. Vatnik, Dmitry V. Churkin +1
We predict a generic mechanism of wave localization at an interface between uniform gauge fields, arising due to propagation-dependent phase accumulation similar to Aharonov-Bohm p…
Laminar-Turbulent Transition in Raman Fiber Lasers: A First Passage Statistics Based Analysis
Amit K Chattopadhyay, Diar Nasiev, Srikanth Sugavanam +2
Loss of coherence with increasing excitation amplitudes and spatial size modulation is a fundamental problem in designing Raman fiber lasers. While it is known that ramping up lase…
Ginzburg-Landau turbulence in quasi-CW Raman fiber lasers
Srikanth Sugavanam, Nikita Tarasov, Stefan Wabnitz +1
Fiber lasers operating via Raman gain or based on rare-earth doped active fibers are widely used as sources of CW radiation. However these lasers are only quasi-CW: their intensity…
Stochasticity, periodicity and coherent structures in partially mode-locked fibre lasers
Dmitry Churkin, Srikanth Sugavanam, Nikita Tarasov +4
Physical systems with co-existence and interplay of processes featuring distinct spatio-temporal scales are found in various research areas ranging from studies of brain activity t…
