Abstract

The controllable focusing property of a flat lens is investigated by changing the external voltage. The tunability is introduced based on electro-optical effect. The flat lens is a slab of photonic crystal composed of air cylinders in electro-optic material background. The results demonstrate that focusing can be achieved by the flat photonic crystal slab. Moreover, the focal length of the flat lens can be tuned continuously by the applied voltage, which might have potential applications in photoelectric devices.
