Popis: International audience; Adaptive atmospheric compensation in laser communication systems can be iteratively addressed minimizing the loop bandwidth requirements. Here we evaluate in the laboratory a speckle-based iterative technique within the framework of a communication scenario. Experimental results show signicant coupling efficiency gain with a reduced number of iterations. Evaluation of the technique with an integrated 80 Gbps QPSK system shows an error probability of 1e-5 for highly turbulent atmospheric channels.
