An active-control optical resonator includes an oxide layer; a ring resonator arranged in a loop and positioned on the oxide layer; a tangential optical waveguide optically coupled to the ring resonator; a translatable body configured to selectively move into an evanescent field region of the ring resonator; a first electrode positioned on the translatable body, the first electrode comprising indium tin oxide; and a second electrode positioned between the oxide layer and the ring resonator.
