In this work, it is shown that for a fixed geometry, it is possible to shift the main resonance frequency by modifying the electrical condition on the electrodes that constitute the cavity's mirrors. The concept was validated by both numerical simulations and experimental characterization of single port resonators fabricated on LiNbO3.Show less >
