Laboratory Validation of Sequential Optimization of Adaptive Receivers in Downlink Laser Communications

Abstract

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.
