Abstract

Subwavelength resonators can enhance nonlinear optical response of laser-excited semiconductors by several orders of magnitude, provide ideal conditions for accessing and exploring qualitatively new physics beyond the perturbative regime, and serve as nanoscale sources for nonlinear frequency conversion. Nonperturbative generation of higher harmonics can be observed in a single subwavelength resonator supporting bound states in the continuum excited by an ultrashort mid-infrared laser beam. Our experimental observations are supported by numerical simulations based on nonperturbative model for electronic excitation.
