For optical fibers exhibiting a radially symmetric refractive index profile, there exists an
analytical relation that connects waveguide dispersion and the Petermann-II mode field …

We analyze the nature of modal cutoff in microstructured optical fibers of finite cross section.
In doing so, we reconcile the striking endlessly single-mode behavior with the fact that in …

We experimentally investigated the limits to the endlessly single-modeness of large mode
area photonic crystal fibers. We analyzed two versions of a commercial large mode area …

A numerical parametric study is used to gain insight into how the shapes of dispersion and
bandwidth spectra are influenced by dimensions and index differences of light-guide …

We investigate how the strongly wavelength-dependent birefringence in nonlinear photonic
crystal fibers leads to a splitting in the zero-dispersion wavelength for the two polarizations …

Exact numerical solutions for the LP_01 propagating mode of the scalar wave equation are
used to calculate propagation constants in single-mode fibers with arbitrary refractive-index …

The propagation of electromagnetic waves along a radially-inhomogeneous single-mode
optical fibre with small index difference between core and cladding is studied. As in the case …

We present the calculations of the higher order dispersion coefficients in a photonic crystal
fiber. The dispersion coefficient is obtained from the calculated effective index of the fiber …

We present very simple expressions for scaling the well-known first-and second-order
modes dispersion curves of circular core fibers in order to predict the propagation …

We propose and demonstrate a novel approach in optical fiber design in which the optical
waveguide is formed by a ring of large air holes surrounding a solid silica core. With an …
