Sensorless adaptive optics for optical communications

Résumé

Mitigation of turbulence-induced disturbances is crucial for high data rate optical links in the atmosphere. Sensorless adaptive optics, based on the optimization of the coupling in a single mode fiber, is a promising solution as it circumvents the limitations of conventional wavefront sensing in strong perturbations. We propose the use of a spatial multiplexer to reduce the bandwidth of the temporal modulation required with such a technique. In this approach, after correction by a deformable mirror, the residual perturbations are analyzed thanks to the multiplexer. The concept and first results of laboratory tests are presented.
