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 ...

TiO_xN_y anti‐resonant layer ARROW waveguides

physica status solidi c, 2010
AbstractARROW waveguides with sputtered‐TiOxNy anti‐resonant layers obtained with different nitrogen concentration in the gaseous mixture were fabricated and characterized. A study of the influence of this parameter on the losses of the waveguides is presented in this work.

Layered SAW Resonators with Near-Zero TCF at Both Resonance and Anti-resonance

2019 IEEE International Ultrasonics Symposium (IUS), 2019
A layered SAW configuration consisting of a thin piezoelectric layer bonded onto a support substrate has been drawing attention for its superior performances—a higher quality factor (Q), higher electromechanical coupling factor (k2) and better temperature coefficient of frequency (TCF)—than conventional SAW technologies.

Double layer hollow core anti-resonant fiber for small core and low loss characteristics

Conference on Lasers and Electro-Optics, 2017
We study the function of second cladding layer of the tube lattice fiber (TLF) and experimentally demonstrate the important role of the second layer in the reduction of both confinement loss (CL) and bending loss.
