a-SiC:H anti-resonant layer ARROW waveguides

Journal of Optics A: Pure and Applied Optics, 2008
Over the last decades, anti-resonant reflecting optical waveguides (ARROW) have been used in different integrated optics applications. In this type of waveguide, light confinement is partially achieved through an anti-resonant reflection. In this work, the simulation, fabrication and characterization of ARROW waveguides using dielectric films deposited

Effect of Altering Outer-Layer-Tube Thickness in Two-Ring Anti-Resonant Hollow-Core Fibers

Frontiers in Optics / Laser Science, 2020
We report on spectral shifting of the low-loss band when outer-layer-tube thickness in two-ring anti-resonant hollow-core fibers is altered. This indicates that the loss reduction originates from the additional anti-resonant reflection at the outer-layer-tube interface.

Low-loss hollow-core photonic bandgap fiber with isolated anti-resonance layer

Optics Communications, 2019
Abstract In this study, a low-loss hollow-core photonic bandgap fiber (HC-PBF) with an isolated anti-resonance layer is proposed. The fiber cladding structure is the same as that of conventional HC-PBF, while the fiber core is surrounded and formed by an isolated anti-resonance layer which separates the core from the cladding. Simulation results show

Optimized‐geometry ARROW waveguides using TiO₂ as anti‐resonant layer

physica status solidi c, 2010
AbstractThe simulation, fabrication and characterization of ARROW waveguides using dielectric films deposited by Plasma Enhanced Chemical Vapor Deposition (PECVD) and Sputtering techniques, are presented in this work. Amorphous titanium oxide (TiO2) films were used as first cladding layer and silicon oxynitride (SiOxNy) films, as core layer ...
