Small-core photonic crystal fibers with weakly disordered air-hole claddings
N. A. Mortensen, M. D. Nielsen, J. R. Folkenberg +2
Motivated by recent experimental work by Folkenberg et al. we consider the effect of weak disorder in the air-hole lattice of small-core photonic crystal fibers. We find that the b…
Single-mode photonic crystal fiber with an effective area of 600 square-micron and low bending loss
Martin Dybendal Nielsen, Jabob Riis Folkenberg, Niels Asger Mortensen
A single-mode all-silica photonic crystal fiber with an effective area of 600 square-micron and low bending loss is demonstrated. The fiber is characterized in terms of attenuation…
Modeling of realistic cladding structures for air-core photonic band-gap fibers
Niels Asger Mortensen, Martin Dybendal Nielsen
Cladding structures of photonic band-gap fibers often have air-holes of non-circular shape and, typically, close-to-hexagonal air holes with curved corners are observed. We study p…
Photonic crystal fiber design based on the V-parameter
Martin Dybendal Nielsen, Niels Asger Mortensen
Based on a recent formulation of the V-parameter of a photonic crystal fiber we provide numerically based empirical expressions for this quantity only dependent on the two structur…
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…
