Abstract
In certain embodiments, a microelectromechanical (MEMS) device comprises a substrate having a top surface, a movable element over the substrate, and an actuation electrode disposed laterally from the reflective surface. The movable element comprises a deformable layer and a reflective element mechanically coupled to the deformable layer. The reflective element includes a reflective surface. The movable element is responsive to a voltage difference applied between the actuation electrode and the movable element by moving in a direction generally perpendicular to the top surface of the substrate.
