Multi channel Optical Communications

SatEnlight is a project conceived in the laboratories of University of Milano dealing with the development of a innovative and proprietary technology for satellite free-space optical communication. This technology, integrable with traditional optical solutions, implements digital multiplexing of data transmitted through an optical channel, exploiting the Optical Angular Momentum (OAM) property of the electromagnetic radiation (typically imprinting a vortex shape to a laser beam wavefront).

This makes possible to decode information simultaneously received from several lasers. Since the decoding is carried out through an interferometric measurement that analyzes a small portion of the laser wavefront, main focus is to design and produce a receiver with small dimensions compared on other solutions on the market. In conclusion, SatEnlight technology enables optical data transmission from LEO, MEO and GEO both for intersatellite links and downlink. It allows to increase data rate, transmission security and design a receiver simply integrable with current infrastructure.
