We utilize light-matter interactions technological to fabrication three-dimensional micros- and nano-strucutres. A tightly focused laser beam exposes photo-sensitive materials via two- or multi-photon absorption. Subsequent development of the unexposed regions creates free-standing structures. These structures can then be infilled with or converted into metallic or dielectric materials to generat functional materials for photonics.
We study light-matter interactions in three-dimensional nanostructures like photonic crystals and metamaterials to discover and understand novel optical phenomena. E.g., artificial chiral materials can dramatically influence the polarization state of light and photonic quasicrystals possess symmetries not found in nature.
