Abstract
Dark optical states, such as anapoles and bound states in the continuum, have recently attracted great scientific interest, as they can offer strong field enhancement and high resonance quality factors. However, their subradiant nature makes them difficult to study using conventional far-field-based optical techniques. Here, we show how to efficiently use nonlinear optical processes, such as second-harmonic generation and sum-frequency generation, to probe nonradiating states of light in various photonic structures, from individual nanoresonators to periodic metasurfaces.Description
