Electrowetting-actuated optical shutters based on total internal reflection or beam steering. An electrowetting cell contains a conducting liquid and a non-conducting liquid configured to form a liquid-liquid interface extending to the inner walls of the cell. A beam of light is directed to the liquid-liquid interface at an angle near the total internal reflection angle of the interface. Voltage changes the shape of the liquid-liquid interface, without separating it from the inner walls of the cell. Thus, when depending on the voltage applied, the beam is either transmitted in part or substantially totally internal reflected.
