Thin Film AlN Microbolometer for Very Long-Wave Infrared Detection
Vivek Tallavajhula, Zarko Sakotic, Ian Anderson +3
The paper presents a suspended thin‑film aluminum nitride (AlN) microbolometer that exploits resonant phonon absorption near 15 µm for narrowband very long‑wave infrared detection,…
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…
In-Plane Q Anisotropy of Higher-Order XBARs
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…
Gradient Residual Stress in Transferred Thin-Film Lithium Niobate and Its Compenstation 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…
Phononic Combs in Lithium Niobate Acoustic Resonators
Ian Anderson, Jack Kramer, Tzu-Hsuan Hsu +3
Frequency combs consist of a spectrum of evenly spaced spectral lines. Optical frequency combs enable technologies ranging from timing, LiDAR, and ultra-stable signal sources. Micr…
