Wave-breaking-free pulses in nonlinear-optical fibers
TLDR
In this article, the conditions for avoiding wave breaking during pulse propagation in optical fibers were investigated, and it was shown that pulses having a parabolic intensity variation are approximate wave-breaking-free solutions of the nonlinear Schrodinger equation in the high-intensity limit.Abstract:
A qualitative as well as quantitative investigation is made of the conditions for avoiding wave breaking during pulse propagation in optical fibers. In particular, it is shown that pulses having a parabolic intensity variation are approximate wave-breaking-free solutions of the nonlinear Schrodinger equation in the high-intensity limit. A simple expression for the compression factor of a fiber-grating compressor based on parabolic pulses is also derived.read more

Compression of optical pulses chirped by self-phase modulation in fibers
TL;DR: In this article, the results of a theoretical analysis of the self-phase modulation in a single-mode fiber are presented for the achievable compression and compressed pulse quality as functions of fiber length and input pulse intensity.

Optical pulse compression based on enhanced frequency chirping
TL;DR: In this article, the authors show that passage of an intense picosecond pulse through a singlemode optical fiber can cause the pulse to become strongly frequency broadened with a positive chirp (linear frequency sweep) describing essentially all of the energy of the output pulse.

Optical wave breaking of pulses in nonlinear optical fibers
TL;DR: A new effect appears in femtosecond optical pulse compression, using single-mode fibers, that is described as optical wave breaking, which often leads to computational instabilities, but careful numerical simulations give results in excellent agreement with experiment.

Wave breaking in nonlinear-optical fibers
TL;DR: In this paper, an analytical investigation of the interplay between dispersion and nonlinearity in the creation of wave breaking in optical fibers is made, which involves two independent processes: overtaking of different parts of the pulse and the nonlinear generation of new frequencies during overtaking.
