Abstract
This study developed an optic-axis controlling device using electrowetting. The device has three-layered liquid: two types of oil and water, in a glass cell with two electrodes. Voltage applied to the electrodes deformed the liquid-liquid interfaces and laser trajectory through liquid layers was refracted at the interfaces. We experimentally obtained about 3 degree of optic angle change at 80 V of applied voltage. We also numerically solved interface shapes between layers to reveal the relation between applied voltage and interface shapes.
