    Abstract

    We observe record-high efficiency of the second-harmonic generation from AlGaAs nanoantennas fabricated on a transparent substrate and pumped with structured light. The engineered nanoantennas exhibit high-quality optical resonances governed by quasi-bound states in the continuum.
