Liquid prism with dual-interface based on electrowetting effect
Abstract
In this paper, we report a prism with two liquid-liquid interfaces based on electrowetting effect. The prism is filled with two immiscible liquids which form two liquid-liquid interfaces. In the device, the filling liquids from the top to the bottom are conductive liquid, oil and conductive liquid. The shape of the two liquid-liquid interfaces will be changed when different voltages are applied to the opposite sidewalls. Our device is capable of wide-angle beam steering and the function of light beam translational. Our results show that the light beam can be deflected by ∼ 22 . 3 ° (- 11 . 5 ° to + 10 . 8 °) and the translational distance is 3.1 mm (-1.5 mm to +1.6 mm). The proposed prism has a wide application in light detection, telecommunications, light alignment and other industrial applications.
