Generic adaptive optics module for optical communication and quantum key distribution

The rising demand for optical and quantum communication necessitates more optical ground stations (OGS) in ground-based networks. To achieve efficient data reception, standardized adaptive optics systems (AOS) are needed to counter atmospheric turbulence. This paper discusses the development of a Generic Adaptive Optics Module (GAOM) aimed at Free-Space Optical Communication (FSOC). The GAOM project focuses on creating a versatile platform for managing optical laser and quantum communication signals while compensating for atmospheric disturbances to enhance single-mode (SM) fiber coupling. The upcoming tests at ESA’s IZN-1 Tenerife station aim to validate this flexible design for various OGS configurations. Key design features of GAOM include modularity and scalability, ensuring adaptability to different use cases and OGS sizes. The presentation outlines GAOM's core design concepts, AOS architecture, and target performance levels, aiming to significantly enhance OGS efficiency and support the growing demand for advanced optical and quantum communication systems.
