Accurate loss and surface mode modeling in fabricated hollow-core photonic bandgap fibers

We present a method to reconstruct the cross-sectional profile of fabricated hollow-core photonic bandgap fibers from SEM images. For the first time, numerical simulations show a good agreement with measured loss and surface mode position

Hollow core photonic band gap fiber: structural and optical tolerance to preform irregularities

Low loss Hollow Core Photonic Bandgap Fibers require regular structures with high air filling fractions, in principle more susceptible to draw-induced distortions. We investigate their tolerances to fabrication imperfections and identify trade-offs and optimum structures

Combining fluid dynamics and electromagnetics modelling to improve hollow core photonic band gap fibres

We combine two powerful simulation tools to predict geometry and optical properties of Hollow Core Photonic Band Gap fibres from their preform and draw parameters. Broad parametric sweeps allow identifying structures with optimum optical performance

Near-zero radiation induced attenuation in nested anti-resonant nodeless hollow-core fibers at 1550 nm

The first nested anti-resonant hollow-core fiber radiation study is reported. A record near-zero radiation induced attenuation is observed under γ-rays and X-rays. These results open new possibilities for fiber-based applications in radiation environments. </p
