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…
Radial Mode Lithium Niobate Rosen Transformer
Ziqian Yao, Heather Chang, Eric Stolt +4
In this work, we demonstrate the first two-port radial-mode Rosen transformer based on 36Y-cut lithium niobate (LN) for piezoelectric power conversion. The device achieve…
62.6 GHz ScAlN Solidly Mounted Acoustic Resonators
Yinan Wang, Byeongjin Kim, Nishanth Ravi +13
We demonstrate a record-high 62.6 GHz solidly mounted acoustic resonator (SMR) incorporating a 67.6 nm scandium aluminum nitride (Sc0.3Al0.7N) piezoelectric layer on a 40 nm buried…
Bimorph Lithium Niobate Piezoelectric Micromachined Ultrasonic Transducer
Ziqian Yao, Vakhtang Chuluhadze, Zihuan Liu +5
This work demonstrates a prototype bi-layer piezoelectric micromachined ultrasonic transducer (PMUT) based on transferred periodically poled piezoelectric film (P3F) X-cut lithium…
Thermal Endurance of Suspended Thin-Film Lithium Niobate up to 800 °C
Mihir Chaudhari, Lezli Matto, Naveed Ahmed +8
The need for high-temperature piezoelectric microelectromechanical systems (MEMS) requires pushing piezoelectric platforms to their thermal limits. In harsh thermal environments, p…
An 11.7-GHz ScAlN FBAR Filter: Case Study on Scaling Limits and Challenges
Sinwoo Cho, Byeongjin Kim, Lezli Matto +9
This paper reports an 11.7 GHz compact 50 ohm ladder filter based on single layer Scandium Aluminum Nitride (ScAlN) film bulk acoustic resonators (FBARs) with platinum (Pt) electro…
