Simulation and Design Framework for Free-Space Optical Communication

Free-Space Optical (FSO) communication is an enabling technology for high-speed, all-optical next generation networks. FSO offers key benefits over radio frequency systems, including higher data rates, license-free spectrum, and power efficiency. The applications range from terrestrial, connecting remote areas (last mile) and complementing fiber networks, to aerial- and satellite-based architectures with GEO and LEO links.

In this webinar, Shi Li introduces a comprehensive simulation and engineering framework, which is necessary for the design and analysis of terrestrial- and satellite-based FSO links. Several methods for FSO channel modeling will be discussed, including key effects such as scintillation, atmospheric turbulence, and pointing error.

The participants will then gain insights into how these models can be used to simulate, evaluate, and optimize end-to-end FSO system performance based on different application examples, such as satellite up- and downlink.

Finally, an outlook is given showcasing potential FSO use cases for integrated photonics, other technologies, and mitigation techniques for improving signal quality upon detection.
