Abstract

Plasmonic nanostructures can confine light and enhance fields, thus boosting nonlinear optical effects such as second harmonic generation. Our research focuses on the nonlinear effects arising from CdSe quantum dots coupled with plasmonic metasurfaces, made up of cuboid nanoparticles arranged in a rectangular lattice. The study demonstrates a strong reciprocal interaction affecting both linear and nonlinear optical effects, such as photoluminescence, second harmonic generation and white light generation. Thus, our research adds up to the fundamental understanding of nonlinear optical responses from hybrid plasmonic nanosystems.
