Abstract
A method to maximize the coupling efficiency between a collimated, free-space optical signal and a fiber optic waveguide using an active optical element to steer and focus the collimated beam driven by an adaptive controller that periodically auto-calibrates the active optical element's parameters to maximize the measured power received by the waveguide using a gradient ascent optimization algorithm.
