Abstract
An electrostatic microactuator for moving an optical fiber is described and includes an actuator plate with opposed major surfaces and interspersed conductive and nonconductive portions. The actuator plate is physically engaged with the optical fiber so that the fiber moves with the actuator. First and second segmented, conductive, torque stators are disposed adjacent the opposed major surfaces of the actuator plate. Multiphase circuitry is connected to segments of the torque stators for applying phased signals thereto to induce a linear actuating force in the actuator plate. The phased signals applied to the first and second torque stators are balanced so as to positionally balance the actuator plate during its travels.
