Inverse design of light-matter interactions — •Robert Bennett, Jonas Matuszak, and Stefan Yoshi Buhmann — University of Freiburg, Germany

Optimal designs for photonic elements (beamsplitters, demultiplexers etc) are usually found through a combination of intuition, symmetry and previous experience. By contrast, in inverse design optimal geometries are algorithmically discovered, often leading to much higher performance. Such techniques are well-developed in the field of nanophotonics, but have not yet been applied to surface-dependent light-matter interactions such as Casimir-Polder forces or medium-assisted resonance energy transfer (RET). In this talk I will outline a very general approach recently developed in our group that allows us to optimise the observables associated with such phenomena, and give an explicit examples of a design able to increase the RET rate by several orders of magnitude.
