Bimorph Lithium Niobate Thickness-Shear Overtone Film Bulk Acoustic Resonator
Ziqian Yao, Ian Anderson, Tzu-Hsuan Hsu +3
High quality factor () and overtone operation enable narrow-linewidth acoustic devices with multiple discrete frequencies in a single cavity. Maintaining both high and suffi…
In-Plane Q Anisotropy of Higher-Order XBARs in 128°Y-Cut Lithium Niobate
Byeongjin Kim, Ian Anderson, Ruochen Lu
128Y-cut lithium niobate (LN) laterally field-excited higher-order antisymmetric bulk acoustic resonators (XBARs) have attracted interest for high-frequency acoustic device…
High Coupling Tunable Acoustic Resonators in Monolithic Barium Titanate
Ian Anderson, Agham Posadas, Alexander A. Demkov +1
The growing number of wireless communication bands has driven demand for compact, low-loss, and frequency adjustable RF filtering. Tunable acoustic resonators are well suited to ad…
Thin Film AlN Microbolometer for Very Long-Wave Infrared Detection
Vivek Tallavajhula, Zarko Sakotic, Ian Anderson +3
We demonstrate a suspended thin-film aluminum nitride (AlN) microbolometer for narrowband very long-wave infrared detection. The device uses a 100-nm-thick AlN membrane suspended a…
Gradient Residual Stress in Transferred Thin-Film Lithium Niobate and Its Compensation Using Periodically Poled Piezoelectric Bilayers
Byeongjin Kim, Ian Anderson, Tzu-Hsuan Hsu +1
In this work, we experimentally investigate the gradient stress (sigma1) in 128 deg Y-cut transferred thin film lithium niobate (TFLN) films with thicknesses from 100 to 460 nm usi…
Nonlinear Characterization of Thin-Film LiNbO3 Acoustic Filters
Omar Barrera, Bryan T. Bosworth, Taran Anusorn +10
Compact, high-performance components in millimeter-wave (mmWave) communication systems demand new acoustic filter technology at increasingly higher frequencies. Among various promi…
Tunable Ferroelectric Acoustic Resonators in Monolithic Thin-Film Barium Titanate
Ian Anderson, Agham Posadas, Alexander A. Demkov +1
The increasing development of wireless communication bands has motivated the development of compact, low-loss, and frequency adjustable RF filtering technologies. Acoustic resonato…
Lattice XBAR Filters in Thin-Film Lithium Niobate
Taran Anusorn, Byeongjin Kim, Ian Anderson +2
This work presents the demonstration of lattice filters based on laterally excited bulk acoustic resonators (XBARs). Two filter implementations, namely direct lattice and layout-ba…
Uncooled low-noise thin-film optomechanical resonator for thermal sensing on lithium niobate
Yue Yu, Ran Yin, Ian Anderson +9
Optomechanical transduction harnesses the interaction between optical fields and mechanical motion to achieve sensitive measurement of weak mechanical quantities with inherently lo…
