We report an experimental technique for determining phase-resolved radiation patterns of single nanoantennas by phase-retrieval defocused imaging. A key property of nanoantennas is their ability to imprint spatial coherence, for instance, on fluoresc

Obtaining nanoscale spatial information without real-space imaging, but from diffraction patterns, is already a valuable tool in metrology We investigate the potential of metasurfaces for nano-optical sensing and metrology with subwavelength resoluti

Nanophotonics VIII.
Cathodoluminescence spectroscopy (CL) is a unique technique to probe optical modes at the nanoscale. The electric field surrounding a 10-30 keV electron beam dynamically polarizes matter, creating optical excitations over the 0-10 eV spectral range,

We study theoretically the scattering of light by an ensemble of $N$ resonant atoms in a sub-wavelength volume. We consider the low intensity regime so that each atom responds linearly to the field. While $N$ non-interacting atoms would scatter $N^2$

We investigate how partial knowledge of scattering nanostructures enables extraction of spatial information from far-field radiation patterns. A reconstruction technique based on singular value decomposition allows localisation of a point-like light

We study two-dimensional hexagonal photonic lattices of silicon Mie resonators with a topological optical band structure in the visible spectral range. We use 30 keV electrons focused to nanoscale spots to map the local optical density of states in t
