Paper Abstract

We describe an adaptive optical fiber coupling system for free- space optical communication comprising a micro-electromechanical deformable mirror and a VLSI gradient descent controller for model-free performance optimization. A comparison of Strehl ratio maximization with direct model-free coupling efficiency optimization revealed an advantage of the latter method.
