09.02.2021 Second-order nonlinear optics, in particular Second-Harmonic Generation (SHG) is the base for a large variety of devices aimed at the active manipulation of light. Within an European collaboration we demonstrate that embedding chromophores in conical silica nanopores results in a photonic metamaterial exhibiting SHG, see the article entitled "Anisotropic confinement of chromophores induces second-order nonlinear optics in a nanoporous photonic metamaterial", published in Optics Letters.
