TLDR
Using computer simulations, results indicate that both the cubic-dispersion term and the shock term of the nonlinear Schrödinger equation contribute to asymmetry in the pulse power spectrum and cause highly nonlinear chirp.Abstract:
Using computer simulations, we examine the effects of higher-order dispersive and nonlinear propagation processes on the spectral and time development of ultrashort, high-intensity pulses propagating in single-mode optical fibers having normal dispersion. Our results indicate that both the cubic-dispersion term and the shock term of the nonlinear Schrodinger equation contribute to asymmetry in the pulse power spectrum and cause highly nonlinear chirp.read more

Beneficial impact of wave-breaking for coherent continuum formation in normally dispersive nonlinear fibers
TL;DR: In this article, the temporal and spectral impact of optical wave-breaking in the development of a continuum was investigated, and the impact of linear losses or gain on the evolution of a pulse propagating in a normally dispersive fiber in the presence of Kerr nonlinearity.

TL;DR: With those pulses, the sub-mJ carrier envelope phase (CEP) stable 1.6 cycle pulses are reported, which have obtained 160eV cut-off in argon at an intensity of 1.4×10 W/cm using the process of high harmonic generation.

Soliton behavior for a generalized mixed nonlinear Schrödinger model with N-fold Darboux transformation
TL;DR: A spectral problem, the x-derivative part of which is a simple generalization of the standard Ablowitz-Kaup-Newell-Segur and Kaup- newell spectral problems, is presented with its associated generalized mixed nonlinear Schrödinger (GMNLS) model and the N-fold Darboux transformation with multi-parameters for the spectral problem is constructed with the help of gauge transformation.

Soliton switching and multi-frequency generation in a nonlinear photonic crystal fiber coupler.
TL;DR: A vector finite element method (FEM) has been developed to precisely calculate the dispersion along with coupling length of the guided modes and the PCF coupler geometry was carefully designed so that it can support soliton pulses.

Solitons for a generalized sixth-order variable-coefficient nonlinear Schrödinger equation for the attosecond pulses in an optical fiber
TL;DR: Investigation of a sixth-order variable-coefficient nonlinear Schrodinger equation, which could describe the attosecond pulses in an optical fiber, shows that the velocities and shapes of the solitons and boundsolitons are both affected by the sixth- order dispersion term.

Discovery of the soliton self-frequency shift.
TL;DR: The experimental discovery of a continuous shift in the optical frequency of a soliton pulse as it travels down the fiber is described, caused by a Raman self-pumping of the soliton.

Theory of the soliton self-frequency shift.
TL;DR: The theory of Raman effects, which causes a continuous downshift of the mean frequency of pulses propagating in optical fibers, agrees well with recent measurements.
