Interaction of light and matter involves transfer of conserved quantities such as energy, momentum, angular momentum etc. Plasmon drag effect (PLDE), the giant enhancement of photoinduced currents in plasmonic metals at surface plasmon resonances (SPR), allows for a systematic study of these fundamental transfer processes. Understanding of exactly how to control this transfer through material properties, precise nanostructuring and/or illumination conditions in one of the main goal of photonics and will bring unprecedented advances in sensing, detection and processing of hybrid optoelectronic signals for applications ranging from new generation computers to electronic output optical biosensors and structured light detectors. Advanced design allows for creating ultimately thin metasurface wave plates, which are capable of complete transformation of polarization of light by 30 nm thick metasurfaces and at the same time makes possible mesoscopic metal-dielectric structures which exhibit optical neutrality, i.e. do not affect light passing through them.
