Multifunction portable ground station for QKD using adaptive optics

Abstract

Power coupling to SMF is vital when using a SNSPD because they are normally used as the light input to the cryostat, in order to minimize dark counts. When the communication optical link is expected to suffer atmospheric turbulence during its free-space path, being able to compensate them could improve the coupling efficiency by a factor between 2 and 10. Laboratory tests showing this improvement in practice will be reported. The design of a Multi-function Optical Ground Station, capable of receiving a quantum key from a satellite and also capable of exchanging them with another station will be outlined as well

Luis Fernando Rodríguez Ramos joined IAC in 1983 and became Head of the Electronics in 1991, being also responsible of its laboratories and of a team of 16 engineers plus 5 technicians.He has been involved in R&D for Adaptive Optics for more than 30 years, pioneered (2005) the use of FPGAs for the calculations required by an adaptive optics system, which was used in the EDIFISE project with an 11x11 actuator deformable mirror. He proposed the use of the Plenoptic Camera as wavefront sensor, adequate for extended objects. He is also deeply involved in the adaptive optics studies and prototyping for the European Solar Telescope, and for the GTC telescope (GTCAO-LGS). He participated in the PAT development for the ESA’s Optical Ground Station Telescope and he supervised the PhD thesis where the first uplink correction of a Laser Guide star was obtained.He is Lead Electronics Engineer for the HARMONI instrument for ELT, and PI of the free-space optical communications projects at IAC
