ML-assisted Subband Learned Digital Backpropagation for Nonlinearity Compensation in Wideband Optical Systems
Evgeny Shevelev, Oleg Sidelnikov, Vitaly Danilko +2
Digital backpropagation (DBP) is one of the most effective techniques for compensating nonlinear distortions in coherent optical fiber communication systems. However, its practical…
Low-complexity neural network equalization for long-haul coherent transmission with cascaded semiconductor optical amplifiers
S. Bogdanov, S. Sygletos, O. Sidelnikov +3
In this letter, we numerically investigate a long-haul coherent data transmission system with a cascade of semiconductor optical amplifiers (SOAs). We exploit low-complexity neural…
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…
Kerr beam self-cleaning in the multimode fiber anomalous dispersion regime
Y. Leventoux, A. Parriaux, O. Sidelnikov +13
We experimentally demonstrate Kerr beam self-cleaning in the anomalous dispersion regime of graded-index multimode optical fibers. By using 90 ps duration, highly chirped (2 nm ban…
