Observation of Soliton Fission in Dispersion Oscillating Fiber

Alexej Sysoliatin Andrew Senatorov Andrey Konyukhov Leonid A. Melnikov Vladimir Stasuyk

A new method of increasing of pulse repetition rate by means of fission of second-order solitons in the fiber with periodically modulated dispersion is studied numerically and experimentally. Good agreement between theory and experiment was obtained.

Modeling of Transverse Beam Dynamics in Photonic Crystal Fibre Laser

Advanced Solid-State Photonics (2005)

Andrey Konyukhov Leonid A. Melnikov

The dynamics of few-mode photonic crystal fibre laser was investigated numerically using the field decomposition in terms of Laguerre-Gaussian functions. The switching of transverse beam structure is observed and dependence on initial conditions is found.

Inelastic collision and fusion of optical solitons in dispersion oscillating fiber

Laser Physics Letters (2015)

Andrey Konyukhov M. A. Dorokhova Leonid A. Melnikov Alexander Plastun

We show through numerical simulations that dispersion oscillating fibers can be used for the fusion of fundamental solitons into high-intensity pulse. Three particular cases are considered: fusion of two co-propagating fundamental solitons, fusion of three co-propagating fundamental solitons and merge of two colliding solitons into breather bound state. Generation of high-intensity pulse is associated with the formation of distinct high-amplitude soliton.

Controlling the interaction between optical solitons using periodic dispersion variations in an optical fibre

Quantum Electronics (2015)

Andrey Konyukhov M. A. Dorokhova Leonid A. Melnikov Alexander Plastun

This paper considers interaction between two fundamental optical solitons in an optical fibre with a periodically varying dispersion. Numerical simulation results indicate that, by properly adjusting the modulation period, one can change the type of interaction between solitons. We consider three particular cases: the fission of a soliton pair into two separate pulses, the generation of an intense pulse as a result of the fusion of two solitons and the formation of a coupled state of two solitons (soliton molecule). The present findings demonstrate the possibility of controlling the number and group velocity of solitons using passive single-mode optical fibres.

Difference-frequency generation in a dual-wavelength semiconductor disk laser: Model with delayed feedback

Quantum Electronics (2019)

Yu. A. Morozov М. И. Балакин L. A. Kochkurov Andrey Konyukhov M. Yu. Morozov

Abstract We have constructed a mathematical model of an intracavity difference-frequency generator based on a dual-wavelength semiconductor disk laser in the form of a time-delay dynamic system. Steady-state lasing (the equilibrium state of the dynamic system), its stability, and also transient dynamics after switching on the primary optical pump source are investigated. It is shown that the equilibrium state is stable in a wide range of parameters, which is of interest for possible applications of such a generator.
