Invited Paper
Complex Functional Nanooptics and Plasmonics – from Fundamentals to Applications

Harald Giessen 4th Physics Institute and Research Center SCoPE, University of Stuttgart, Stuttgart, Germany

Nanooptics has experienced tremendous growth over the last few years. The possibility to tailor materials and their dielectric and optical properties from the bottom up on the subwavelength level has opened the door to ultimate control of light-matter interaction. This holds true for the linear optical properties, as well as for optical nonlinearities. Particularly, plasmonics allows for large electric field confinement and enhancement on the sub-100 nm length scale. Specifically, the combination of a variety of geometrical shapes and structures has enabled optical resonance tailoring, for example by utilizing narrow Fano resonances. Novel functionalities such as plasmonic chirality, leading to giant optical activity, can be attained through geometrical arrangement of simpler plasmonic building blocks. Hybrid plasmonic structures, which involve additional elements such as active phase-change, nonlinear, or magneto-optical materials, give control over the dynamical behavior of nanoscopic light-matter interaction. In this talk, I will focus on novel applications that involve a combination of hybrid and functional plasmonics, as well as active and reconfigurable nanooptics. Also, combining novel low-cost and large-area fabrication methods opens the door towards applications.
