Sub-diffraction limited localization of self-interacting nanoparticles above a mirror
By placing fluorescent nanoparticles above a mirror, the microscopy image depends sensitively on the axial position of the nanoparticle, which can be used for a sub-diffraction limited localization. A numerical simulation with JCMsuite shows that the localization sensitivity is an effect of the single emitter's interference with its own mirror image.

Metasurface-enhanced photon upconversion upon 1550 nm excitation
Erbium ions (Er3+) used for photon upconversion suffer from a low absorption cross-section and a low brightness. The ability of silicon metasurfaces to provide greatly enhanced electrical near-fields is employed to gain a more than 2400-fold enhanced photon upconversion. With the aid of optical simulations using JCMsuite, the enhancement is attributed to the excitation of metasurface resonances from specific incident angles.
