Over the past few years, progress in hollow-core optical fiber technology has reduced the
attenuation of these fibers to levels comparable to those of all-solid silica-core single-mode …

In this paper a flexible hollow core waveguide for the terahertz spectral range is
demonstrated. Its cladding is composed of a circular arrangement of dielectric tubes …

We use numerical simulations to investigate how the curvature of the fiber core boundary
influences the attenuation of hollow antiresonant fibers. We show the importance of a …

Over the past few years, progress in hollow-core optical fiber technology has reduced the

We report high performance nodeless hollow-core anti-resonant fibers (HARFs) with
broadband guidance from 850 nm to> 1700 nm and transmission attenuation of~ 100 dB/km …

In this paper we evaluate the cut-off properties of holey fibers (HFs) with a triangular lattice of
air holes and the core formed by the removal of a single (HF1) or more air holes (HF3 and …

In this paper, we demonstrate and report a photonic crystal fiber (PCF) infiltrated with PDMS
elastomer which is sensitive to external bending and temperature perturbations. Numerical …

We present a numerical analysis on bending-induced loss and bending-enhanced higher-
order mode suppression in negative curvature fibers. We provide underlying mechanisms …

In view of its feasibility for fabrication and application, a bend-resistant large-mode-area
photonic crystal fiber with a triangular core is proposed. In our design, the fiber proposes a …

A single-mode photonic crystal fiber (PCF) with low chromatic dispersion, low bend, and
rotational sensitivity is presented. The transverse electric field vector distributions of the …
