Ultraviolet Light-Induced Microwave Mode Tuning in a Rutile TiO${}_2$ 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${}_2$, demonstrating strong optical-microwave t…
