Abstract:
A broadband beam steering device using the dielectrophoresis-tilted prism of liquids is demonstrated. Dielectric force is utilized to slant the interface to imitate the refractive behavior of a prism. The steering angle increases as the applied voltage increases. Two dimensional beam steering is also successfully achieved by stacking two devices in orthogonal positions. The broadband feature is demonstrated using two collinear green and red laser beams.
