Propagation of Light in Photonic Crystal Fibre Devices
Ali Dabirian, Mahmood Akbari, Niels Asger Mortensen
We describe a semi-analytical approach for three-dimensional analysis of photonic crystal fibre devices. The approach relies on modal transmission-line theory. We offer two example…
The radiated fields of the fundamental mode of photonic crystal fibers
Ali Dabirian, Mahmood Akbari, Niels Asger Mortensen
The six-fold rotational symmetry of photonic crystal fibers has important manifestations in the radiated fields in terms of i) a focusing phenomena at a finite distance from the en…
Semi-analytical approach to short-wavelength dispersion and modal properties of photonic crystal fibers
Niels Asger Mortensen
We consider photonic crystal fibers made from arbitrary base materials and derive a unified semi-analytical approach for the dispersion and modal properties which applies to the sh…
A Coupled Cavity Micro Fluidic Dye Ring Laser
M. Gersborg-Hansen, S. Balslev, N. A. Mortensen +1
We present a laterally emitting, coupled cavity micro fluidic dye ring laser, suitable for integration into lab-on-a-chip micro systems. The micro-fluidic laser has been successful…
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…
