Approaches to mitigation of atmospheric fluctuations for free-space optical channels
FY 2020-21 · 2021-03-30
Summary
Mitigation of atmospheric fluctuations is an absolute necessity for the full benefits of high bandwidth (> 1 Tbs) satellite-based optical communications to be realized. For observational astronomy, the impact of atmospheric fluctuations is well-managed by the implementation of adaptive optics, which is now a mature technology. For satellite-based optical communications, the same solution is not sufficient to mitigate the impact of atmospheric fluctuations in the high turbulence regime, particularly for high bandwidth applications. In particular, a high degree of phase recovery is required in order to fully benefit from a large collection area while also enabling optical focusing to a diffraction-limited spot as required for high bandwidth coherent optical processing. In the Project, new optical detection systems and signal processing approaches suitable for high bandwidth satellite-based optical communications will be developed.

Description (French)
La réduction de l’impact des fluctuations atmosphériques est une nécessité absolue pour tirer pleinement parti des communications optiques par satellite à large bande (> 1 Tb/s). Pour l’astronomie observationnelle, l’impact des fluctuations atmosphériques est bien géré par la mise en œuvre de l’optique adaptative, qui est maintenant une technologie mature. Pour les communications optiques par satellite, la même solution n’est pas suffisante pour atténuer l’impact des fluctuations atmosphériques dans le régime de forte turbulence, en particulier pour les applications à large bande passante. Il faut notamment un degré élevé de récupération de phase pour tirer pleinement parti d’une grande surface de collecte tout en permettant la focalisation optique sur un point limité par la diffraction, comme l’exige le traitement optique cohérent à large bande. Dans le cadre du projet, de nouveaux systèmes de détection optique et des stratégies de traitement du signal adaptés aux communications optiques par satellite à large bande passante seront formulées.
