Hybrid Plasmonic Nanostructures with Unconventional Nonlinear Optical Properties

A hybrid nonlinear optical component is described based on a Au–PAA metal–dielectric assembly, which exhibits unconventional self-defocusing and inverse optical switching behavior. This heteronanostructure realizes SPR-induced nonlinear optics that enable an ultra-low threshold and an extraordinarily high nonlinear response. Such an SPR-induced nonlinear response can be further mani­pulated by more complex host–guest configuration such as Au–PAA–Au–C60.
