From scanning-electron microscope images of the cross section of a photonic-bandgap fiber (NKT Photonics' HC-1550-02) we developed a realistic model for its permittivity profile that includes all observable structural deformations in the core and in

A full-vectorial finite-difference scheme utilizing the hexagonal Yee's cell is used in this paper to analyze the modes of photonic-bandgap fibers with C6 v symmetry. Because it respects the fiber's native symmetry, this method is free from any numer

Using a new full-vectorial finite-difference mode solver utilizing a hexagonal Yee's cell, we calculated the dispersion diagram of a slightly multimode (16 modes) air-core photonic-bandgap fiber (PBF) and the electric-field profiles of all of its cor

Using a novel matrix formulation, the equi-frequency diagrams of an arbitrary two-dimensional photonic crystal have been computed. In addition, using a frequency domain technique, a two-dimensional photonic crystal slab illuminated by a Gaussian beam

Using a linear combination of properly chosen spatial harmonics, we present a solution to Maxwell's equations which lends itself to the diffraction analysis of periodic structures. The proposed formulation is in a one-to-one correspondence with the w

In this paper, we study the rotation sensitivity of a gyroscope made of a two -dimensional array of coupled resonators consisting of N columns of one -dimensional coupled resonant optica l waveguides (CROWs) connected by two bus waveguides, each CROW

Multiple-scale analysis is employed for the analysis of plane wave refraction at a nonlinear slab. It will be demonstrated that the perturbation method will lead to a nonuniformly valid approximation to the solution of the nonlinear wave equation. To

We use coupled-mode theory with strong perturbation to model the loss and backscattering coefficients of a commercial hollow-core fiber (NKT Photonics’ HC-1550-02 fiber) induced by the frozen-in longitudinal perturbations of the fiber cross section

To understand the loss limitations of a splice between a hollow-core fiber and a conventional fiber, we use a numerical model to calculate the expected coupling loss between the NKT Photonics' HC-1550-02 fiber and a single-mode fiber (SMF) of arbitra
