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…
Pattern generation by dissipative parametric instability
A. M. Perego, N. Tarasov, D. V. Churkin +2
Nonlinear instabilities are responsible for spontaneous pattern formation in a vast number of natural and engineered systems ranging from biology to galaxies build-up. We propose a…
