EELS simulations of dielectric photonic nanocavities
In a recent study of optical nanocavities, made from dielectric silicon, using low-loss electron energy-loss spectroscopy (EELS), we identified that the EELS data give valuable insights into different optical eigenmodes with a spatial resolution of a few 10s of nanometers – so far below the diffraction limit. While previously we focused on the spectral peaks, it turns out that spectral dips may also be interesting. The aim in this project will be to investigate the dips via simulation of the EEL spectra. Towards this goal, a previously-developed COMSOL approach will be adapted and applied to our experimental case. It is noted that extensive experimental data is already available for comparison with, and validation of, the EELS simulations. Note that this project is suitable for the EPFL minor in photonics.
