Abstract

Free-space optical links are important for “last-mile” connectivity of future classical and quantum networks, in locations where it is impractical or too costly to run optical fibre. In this presentation, we will discuss the challenges such links present, and strategies for overcoming these. Results of a building-to-building test of such a link over approximately 150 m will be presented.
