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…

Improving efficiency of supercontinuum generation in photonic crystal fibers by direct degenerate four-wave-mixing
N. I. Nikolov, O. Bang, A. Bjarklev
We numerically study supercontinuum (SC) generation in photonic crystal fibers pumped with low-power 30-ps pulses close to the zero dispersion wavelength 647nm. We show how the eff…
