Abstract
The following relates generally to optical voltage sensing, and in particular to optical voltage sensing of power grids and of a subject body. For example, some embodiments include an optical resonator comprising: (i) a top electrode layer, (ii) a piezoelectric layer, and (iii) a substrate. A light source may illuminate the optical resonator of the voltage sensor with light comprising an incident optical power at an input wavelength, where the input wavelength is offset from a resonant wavelength of the optical resonator by a baseline voltage. The applied voltage may then be measured by measuring a reflected or transmitted light power.
