Nanostructures and optics

Numerical models

We perform numerical simulations of our photonic structures (opals, planar photonic crystals, Tamm structures) in order to analyze our experimental results and guide our fabrication of new structures. We use in particular plane-wave development techniques (MPB), FDTD – Finite-Difference Time-Domain (Meep) and finite elements methods (COMSOL). We can then predict the stop bands of an opal or an opal with defect, the effect of a photonic structure on the radiative decay rate of a fluorescent emitter, model the hot spots of a plasmonic structure or describe the radiation diagram of a Tamm mode.
