Direct RF to Optical Link Based on Film Bulk Acoustic Wave Resonators (FBAR)

open access: yesConference on Lasers and Electro-Optics, 2016
We demonstrate conversion of a 10GHz radio frequency signal directly to fiber optics. A Fabry-Perot cavity formed between a fiber tip and an AlN-film acoustic resonator electrode enables resonantly enhanced phase modulation of back-reflected light.

Fabrication of Bulk Acoustic Wave Resonator with Multilayer Graphene Electrode

open access: yesphysica status solidi (b), Volume 262, Issue 12, December 2025.
Herein, multilayer graphene structures are grown on the silicon substrate for the fabrication of the bulk acoustic wave resonator device. The result reveals that both methods can be used to replace the Bragg reflector. Two bulk acoustic wave resonator (BAW) devices with multilayer graphene as bottom electrodes are fabricated using the chemical vapor ...

Three-Dimensional Finite Element Analysis and Characterization of Quasi-Surface Acoustic Wave Resonators

open access: yesMicromachines, 2021
In this work, three-dimensional finite element analysis (3D FEA) of quasi-surface acoustic wave (QSAW) resonators with high accuracy is reported. The QSAW resonators consist of simple molybdenum (Mo) interdigitated transducers (IDT) on solidly mounted ...

One watt gallium arsenide class-E power amplifier with a thin-film bulk acoustic resonator filter embedded in the output network

open access: yesThe Journal of Engineering, 2015
Integration of a class-E power amplifier (PA) and a thin-film bulk acoustic wave resonator (FBAR) filter is shown to provide high power added efficiency in addition to superior out-of-band spectrum suppression.

Epitaxial and Fiber‐Textured Stacks of Al0.7Sc0.3N/Mo/AlN Prepared by Magnetron Sputter Epitaxy for Bulk Acoustic Wave Devices: A Comparison using High Overtone Bulk Acoustic Wave Resonator

open access: yesphysica status solidi (a), Volume 222, Issue 16, August 2025.
The study compares high overtone bulk acoustic wave resonators (HBAR) using fiber‐textured and epitaxial Al0.7Sc0.3N/Mo/AlN stacks on Si(111). HBAR fabricated using an epitaxial stack show superior performance, with 25% higher figure of merit due to improved crystal quality and piezoelectric response.

The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics

open access: yesAdvanced Materials Interfaces, Volume 12, Issue 12, June 23, 2025.
Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...
