Low Temperature Properties of Low-Loss Macroscopic Lithium Niobate Bulk Acoustic Wave Resonators
William M. Campbell, Leonardo Mariana, Sonali Parashar +2
We investigate gram scale macroscopic bulk acoustic wave (BAW) resonators manufactured from plates of piezoelectric lithium niobate. The intrinsic competing loss mechanisms were st…

Ultraviolet Light-Induced Microwave Mode Tuning in a Rutile TiO Whispering Gallery Resonator
Catriona A. Thomson, Michael E. Tobar, Maxim Goryachev
We report the observation of transient nonlinear optical effects in a macroscopic whispering gallery mode resonator made of rutile TiO, demonstrating strong optical-microwave t…
