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

Cross-Phase Modulation: A New Technique for Controlling the Spectral, Temporal, and Spatial Properties of Ultrashort Pulses
TL;DR: Self-phase modulation (SPM) as mentioned in this paper is the principal mechanism responsible for the generation of picosecond and femtosecond white-light supercontinua, which can also be generated by a copropagating pulse.

TL;DR: In this paper, the authors present an analytical expression which describes the conversion of a frequency-modulated signal at a transmitter to optical amplitude modulation at a receiver due to fiber chromatic dispersion.
A programmable passive amplifier based on temporal self-imaging (Talbot) effect and application.
TL;DR: The main contribution reported in this thesis resides in the derivation of a non-trivial generalization of the I-TSI equations, which allow for a relatively wide range of different gain factors, or the associated rate-division factors, using a fixed dispersion, by suitably programming the temporal phase modulation step.
