Piezoelectric and electromagnetic actuators for beam alignment and systems and methods using the same

摘要

Systems and methods for actuating optical elements steer a beam in two degrees of freedom in order to efficiently align the beam between a selected input and output. These systems include actuator configurations that have piezoelectric and electromagnetic components, servo control systems, and optical cross connect configurations. The actuable optical elements include reflective surfaces (e.g., mirrors), prisms, lenses, and optical fibers.
