Loss analysis of single-mode fiber splices
TL;DR: In this paper, the authors consider the possibility that the two fibers of different dimensions are separated in longitudinal direction and are tilted or offset with respect to each other, and the trade-off between slice tolerances with regard to tilt and offset is expressed as an uncertainty principle.

Gaussian approximation of the fundamental modes of graded-index fibers
TL;DR: In this article, a direct numerical integration of the wave equation is used to establish the validity of approximating the fundamental mode of graded-index fibers by a Gaussian function, and the fundamental modes of fibers, whose index profile can be expressed as a power law, are indeed very nearly Gaussian in shape.

Dispersion properties of photonic crystal fibers
TL;DR: In this paper, the dispersion properties of silica-based photonic crystal fibers (PCFs) were analyzed to obtain: (i) zero dispersion at any wave length, (ii) nearly zero ultraflattened dispersion, and (iii) very high negative chromatic dispersion for various designs of PCFs.
