Propagation of coupled quartic and dipole multi-solitons in optical fibers medium with higher-order dispersions
Vladimir I. Kruglov, Houria Triki
We present the discovery of two types of multiple-hump soliton modes in a highly dispersive optical fiber with a Kerr nonlinearity. We show that multi-hump optical solitons of quar…
Propagation of periodic and solitary waves in a highly dispersive cubic-quintic medium with self-frequency shift and self-steepening nonlinearity
Vladimir I. Kruglov, Houria Triki
We study the dynamics of femtosecond light pulse propagation in a cubic-quintic medium exhibiting dispersive effect up to the fourth order as well as self-frequency shift and self-…
Periodic and localized waves in parabolic-law media with third- and fourth-order dispersions
Houria Triki, Vladimir I. Kruglov
We study the propagation of femtosecond light pulses inside an optical fiber medium exhibiting higher-order dispersion and cubic-quintic nonlinearities. Pulse evolution in such sys…
Novel solitary and periodic waves in quadratic-cubic non-centrosymmetric waveguides
Houria Triki, Vladimir I. Kruglov
We present a wide class of novel solitary and periodic waves in a non-centrosymmetric waveguide exhibiting second- and third-order nonlinearities. We show the existence of bright,…
Chirped periodic and localized waves in a weakly nonlocal media with cubic-quintic nonlinearity
Houria Triki, Vladimir I. Kruglov
We study the propagation of one-dimentional optical beams in a weakly nonlocal medium exhibiting cubic-quintic nonlinearity. A nonlinear equation governing the evolution of the bea…
Chirped periodic and solitary waves in nonlinear negative index materials
Houria Triki, Vladimir I. Kruglov
Propagation of ultrashort pulses at least a few tens of optical cycles in duration through a negative index material is investigated theoretically based on the generalized nonlinea…
