Ultra-large bandwidth hollow-core guiding in all-silica Bragg fibers with nano-supports
G. Vienne, Y. Xu, C. Jakobsen +12
We demonstrate a new class of hollow-core Bragg fibers that are composed of concentric cylindrical silica rings separated by nanoscale support bridges. We theoretically predict and…
Predicting macrobending loss for large-mode area photonic crystal fibers
M. D. Nielsen, N. A. Mortensen, M. Albertsen +3
We report on an easy-to-evaluate expression for the prediction of the bend-loss for a large mode area photonic crystal fiber (PCF) with a triangular air-hole lattice. The expressio…
Bandwidth comparison of photonic crystal fibers and conventional single-mode fibers
M. D. Nielsen, J. R. Folkenberg, N. A. Mortensen +1
We experimentally compare the optical bandwidth of a conventional single-mode fiber (SMF) with 3 different photonic crystal fibers (PCF) all optimized for visible applications. The…
Mode-Field Radius of Photonic Crystal Fibers Expressed by the V-parameter
M. D. Nielsen, N. A. Mortensen, J. R. Folkenberg +1
We numerically calculate the equivalent mode-field radius of the fundamental mode in a photonic crystal fiber (PCF) and show that this is a function of the V-parameter only and not…
Material effects in airguiding photonic bandgap fibers
Jesper Laegsgaard, Niels Asger Mortensen, Jesper Riishede +1
The waveguiding properties of two silica-based airguiding photonic bandgap fiber designs are investigated with special emphasis on material effects. The nonlinear coefficients are…
Mode areas and field energy distribution in honeycomb photonic bandgap fibers
Jesper Laegsgaard, Niels Asger Mortensen, Anders Bjarklev
The field energy distributions and effective mode areas of silica-based photonic bandgap fibers with a honeycomb airhole structure in the cladding and an extra airhole defining the…
