Mitigation of atmospheric turbulence in optical downlinks using machine learning assisted algorithms and device designs
FY 2022-23 · 2023-03-10
Summary
The project will advance two new commercializable approaches to mitigate effects of atmospheric turbulence on satellite optical downlinks. Intensity based compressive sensing will be implemented for both acquisition/tracking and wavefront sensing. In collaboration with Optiwave, this project will design and prototype the first integrated on-chip wavefront sensing/correction for optical PAGE 6 communication systems. Artificial intelligence (machine learning) will be exploited heavily to explore the large design space, as needed to optimize the performance of compact photonic integrated circuits with subwavelength features. Machine learning methods will also be implemented to train and subsequently control the phase retrieval and correction systems in both approaches. These approaches will be validated in the laboratory and/or by testing their performance with real data that will be obtained using the MDA optical ground receiver. This exciting and innovative project will deliver scalable, cost-effective, and robust solutions to atmospheric turbulence which will enable high speed optical satellite downlinks throughout Canada.

Description (French)
Le projet visera à perfectionner deux nouvelles approches commercialisables pour l’atténuation des effets de la turbulence atmosphérique sur les liaisons optiques satellitaires descendantes. L’acquisition comprimée fondée sur l’intensité autorisera en même temps le suivi et la détection du front d’onde. En collaboration avec Optiwave, nous créerons et testerons un prototype de détection/correction de front d’onde intégrée sur puce pour les systèmes de communication optique. L’intelligence artificielle (apprentissage automatique) sera largement mise à contribution pour explorer les multiples avenues de conception et optimiser les performances des circuits photoniques intégrés compacts présentant les caractéristiques d’un réseau de sous-longueurs d’onde. Des méthodes d’apprentissage automatique seront également mises en œuvre pour le réglage et le contrôle subséquents des systèmes de récupération et de correction de phase dans les deux approches. Ces approches seront validées en laboratoire ou par tests de performance avec des données réelles obtenues à l’aide du récepteur optique terrestre de MDA. Ce projet passionnant et novateur fournira des solutions évolutives, rentables et robustes d’atténuation des effets de la turbulence atmosphérique, et permettra d’établir des liaisons descendantes par satellite optique à haute vitesse à travers le Canada.
