TLDR
The propagation of optical pulses is considered at the zero-dispersion wavelength of nonlinear dispersive fibers of single-mode silica fibers and the evolution of pulse shapes and pulse spectra along the fiber length for a wide range of initial pulse widths is studied.Abstract:
The propagation of optical pulses is considered at the zero-dispersion wavelength of nonlinear dispersive fibers. Even in the absence of group-velocity (first-order) dispersion, higher-order dispersive effects in single-mode silica fibers are found to be strong enough to cause significant broadening and distortion of picosecond optical pulses for fiber lengths of 10\char21{}100 km. Using the parameters appropriate for a 1.55-\ensuremath{\mu}m dispersion-shifted single-mode fiber, we have studied the evolution of pulse shapes and pulse spectra along the fiber length for a wide range of initial pulse widths. For peak powers \ensuremath{\sim}10 mW, the dispersive and nonlinear effects are comparable for pulse widths \ensuremath{\sim}1 ps and their mutual interplay leads to new qualitative features in the pulse shape and spectrum that are largely independent of the input profile. The theoretical results are useful for an understanding of the higher-order dispersion and, at the same time, have implications for high-capacity, long-haul, optical communication systems.read more

Dissipative light bullets: From stationary light bullets to double, quadruple, sixfold, eightfold and tenfold bullet complexes
TL;DR: Stability of three dimensional spatiotemporal solitons (“dissipative light bullets”) in highly nonlinear doped Kerr media with higher-order dispersion terms is analyzed and it is demonstrated that, using an elliptic initial condition, solutions may be stable or unstable.

TL;DR: In this paper, the authors discuss the practical conditions needed for an optical pulse to become a soliton in a dielectric waveguide and show that in a real three-dimensional fiber, the light wave propagates with finite loss.

TL;DR: In this article, the authors demonstrate supercontinuum generation in a liquid-core microstructured optical fiber using carbon disulfide as the core material and demonstrate an extraordinary high conversion efficiency from pump to soliton and to dispersive wave, overall defining a platform that enables studying the impact of noninstantaneous responses on ultrafast soliton dynamics and coherence using straightforward pump lasers and diagnostics.
