Abstract
A photonic device may include a pair of piezoelectric actuators, a waveguide suspended between and mechanically coupled to the pair of piezoelectric actuators, and a voltage source configured to apply an actuation voltage to the pair of piezoelectric actuators to induce longitudinal motion in each actuator of the pair of piezoelectric actuators. The longitudinal motion of the pair of piezoelectric actuators may induce lateral motion in the waveguide. In addition, the photonic device may include optoelectronic element that is spatially separated from the waveguide by a coupling gap. The lateral motion induced in the waveguide may reduce the size of the coupling gap for evanescently coupling the waveguide to the optoelectronic element during operation.
