Nonlinear optical pulses in media with asymmetric gain
Sergei K. Turitsyn, Anastasia E. Bednyakova, Evgeniy V. Podivilov
A generic novel model governing optical pulse propagation in a nonlinear dispersive amplifying medium with asymmetric (linear spectral slope) gain is introduced. We examine the pro…
Thermalization of orbital angular momentum beams in multimode optical fibers
E. V. Podivilov, F. Mangini, O. S. Sidelnikov +7
We present a general theory of thermalization of light in multimode optical fibers, including optical beams with nonzero orbital angular momentum or vortex beams. A generalized Ray…
Random Mode Coupling Assists Kerr Beam Self-Cleaning in a Graded-Index Multimode Optical Fiber
Oleg S. Sidelnikov, Evgeniy V. Podivilov, Mikhail P. Fedoruk +1
In this paper, we numerically investigate the process of beam self-cleaning in a graded-index multimode optical fiber, by using the coupled-mode model. We introduce various models…
Hydrodynamic 2D turbulence and spatial beam condensation in multimode optical fibers
E. V. Podivilov, D. S. Kharenko, V. A. Gonta +6
We show that Kerr beam self-cleaning results from parametric mode mixing instabilities, that generate a number of nonlinearly interacting modes with randomized phases -- optical wa…
Dissipative soliton comb
Evgeniy V. Podivilov, Denis S. Kharenko, Anastasia E. Bednyakova +2
Dissipative solitons are stable localized coherent structures with linear frequency chirp generated in normal-dispersion mode-locked lasers. The soliton energy in fiber lasers is l…
Selective excitation of plasmons superlocalized at sharp perturbations of metal nanoparticles
M. V. Gorkunov, B. I. Sturman, E. V. Podivilov
Sharp metal corners and tips support plasmons localized on the scale of the curvature radius -- superlocalized plasmons. We analyze plasmonic properties of nanoparticles with small…
