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

Beam Propagation Method
TL;DR: The beam propagation method (BPM) as mentioned in this paper is the most powerful technique to investigate linear and nonlinear light wave propagation phenomena in axially varying waveguides such as curvilinear directional couplers, branching and combining waveguide, S-shaped bent waveguide and tapered waveguide.

Solitons near the zero dispersion wavelength of single-mode fibers
TL;DR: In this article, the authors proposed to use the nonlinearity of the refractive index, the Kerr effect, to balance the second-order dispersion in a single-mode silica fiber.

Optical Properties of Microstructure Optical Fibers
TL;DR: The most basic design of an optical fiber consists of silica cladding that surrounds a silica core doped with germanium, which increases the index of refraction by up to 2% above that of pure silica, allowing light to be guided by total internal reflection at the core-cladding interface as discussed by the authors.
