All-dielectric nanostructures have thrived in recent years as a promising and effective alternative to plasmonic nanoantennas to manipulate light–matter interactions at the nanoscale. With no material dissipation, in principle, and controlled radiation losses, all-dielectric nanostructures support a range of novel resonating phenomena including Mie resonances, bound states in the continuum, and anapole modes. Their advantages have been demonstrated in a range of novel applications (e.g. fluorescence enhancement, nonlinear optics, sensing).

In this thematic issue, we invite contributions on theoretical, numerical, and experimental investigations of various optical phenomena based on all-dielectric nanostructures, with an emphasis on the exploration of new resonating behaviors and novel applications of all-dielectric nanostructures to manipulate optical processes across the whole electromagnetic spectrum.

The submitted manuscripts are expected to contain, but are not limited to, the following topics:

• Reviews on general nano-optics based on all-dielectric nanostructures.
• Theoretical and numerical investigations of novel optical resonances.
• Novel structure design to support controlled resonances.
• Strong coupling of matter excitations and optical resonances.
• Hybrid nanostructures involving both plasmonic and dielectric components.
• All-dielectric nanoscale optoelectronic devices.
• Applications of various resonances supported by all-dielectric nanostructures.
