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…
Periodically Poled Piezoelectric Lithium Niobate Resonator for Piezoelectric Power Conversion
Ziqian Yao, Clarissa Daniel, Lezli Matto +8
As the demand for compact and efficient power conversion systems increases, piezoelectric power converters have gained attention for their ability to replace bulky magnetic inducto…
High-Q Millimeter-Wave Acoustic Resonators in Thin-Film Lithium Niobate Using Higher-Order Antisymmetric Modes
Vakhtang Chulukhadze, Jack Kramer, Tzu-Hsuan Hsu +2
This letter presents miniature millimeter wave (mmWave, above 30 GHz) acoustic resonators based on a single-layer thin-film lithium niobate (LN) platform. More specifically, we pre…
Thin-film scandium aluminum nitride bulk acoustic resonator with high Q of 208 and K2 of 9.5% at 12.5 GHz
Sinwoo Cho, Yinan Wang, Eugene Kwon +9
This work describes sputtered scandium aluminum nitride (ScAlN) thin-film bulk acoustic resonators (FBAR) at 12.5 GHz with high electromechanical coupling (k2) of 9.5% and quality…
Lithium Tantalate Bulk Acoustic Resonator For Piezoelectric Power Conversion
Ziqian Yao, Clarissa Daniel, Eric Stolt +3
We present the first lithium tantalate (LT) thickness-extensional (TE) mode bulk acoustic resonators designed for piezoelectric power conversion, showcasing a low temperature coeff…
Acoustic resonators above 100 GHz
Jack Kramer, Bryan T. Bosworth, Lezli Matto +8
Piezoelectric resonators are a common building block for signal processing because of their miniature size, low insertion loss, and high quality factor. As consumer electronics pus…
