摘要： A package for moving a platform in six degrees of freedom, is provided. The platform may include an optoelectronic device mounted thereon. The package includes an in-plane actuator which may be a MEMS actuator and an out-of-plane actuator which may be formed of a piezoelectric element. The in-plane MEMS actuator may be mounted on the out-of-plane actuator mounted on a recess in a PCB. The in-plane MEMS actuator includes a plurality comb structures in which fingers of opposed combs overlap one another, i.e. extend past each other's ends. The out-of-plane actuator includes a central portion and a plurality of surrounding stages that are connected to the central portion. The in-plane MEMS actuator is coupled to the out-of-plane Z actuator to provide three degrees of freedom to the payload which may be an optoelectronic device included in the package.
