Optical energy transfer between separate systems is a process of key importance in nanooptics. It accounts for short-range interactions between a local probe and a target, e.g. a molecule or a sample. Optical energy transfer is also encountered in photosynthesis, in the interaction between semiconductor quantum structures, and it is the basis for FRET, a widely used technique to measure nanoscale distances. In this lecture a classical theory for energy transfer will be derived, and the so-called weak and strong coupling regimes will be discussed, as well as present examples where energy transfer is used to monitor nanoscale processes.
