Abstract
A tunable optical electrowetting element having a liquid-liquid interface shape controlled by an applied voltage. Circuitry for applying a voltage to the electrowetting element is configured to apply a shaped voltage signal comprising a first fast-rising signal combined with a second fast-rising signal. The second signal is selected to damp oscillations in the liquid-liquid interface caused by the first signal.
