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…
Low-loss photonic crystal fibers for transmission systems and their dispersion properties
M. D. Nielsen, C. Jacobsen, N. A. Mortensen +2
We report on a single-mode photonic crystal fiber with attenuation and effective area at 1550 nm of 0.48 dB/km and 130 square-micron, respectively. This is, to our knowledge, the l…
Polarization maintaining large mode area photonic crystal fiber
J. R. Folkenberg, M. D. Nielsen, N. A. Mortensen +2
We report on a polarization maintaining large mode area photonic crystal fiber. Unlike, previous work on polarization maintaining photonic crystal fibers, birefringence is introduc…
Photonic crystal fiber with a hybrid honeycomb cladding
N. A. Mortensen, M. D. Nielsen, J. R. Folkenberg +2
We consider an air-silica honeycomb lattice and demonstrate a new approach to the formation of a core defect. Typically, a high or low-index core is formed by adding a high-index r…
