Empirical relations for far-field characterization of photonic crystal fibers
Titas Das,Somenath Sarkar +1 more
TL;DR: In this article, the authors present simple empirical relations for angle of beam divergence of a solid-core photonic crystal fiber (PCF) only depending on the opto-geometrical parameters like wavelength of the light used and the two structural parameters, the air hole diameter and the hole pitch.

Choice of Step and Near Step Profiles from Splice Loss Analysis of Trapezoidal Index Single Mode Fibers Leading to a Proposal of a Longitudinal Displacement Sensor
TL;DR: In this paper , the effect of aspect ratio on splice loss between a pair of identical single mode trapezoidal index fibers in the presence of longitudinal and transverse misalignments is investigated.

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.
