Abstract

Resonant plasmonic structures and metasurfaces hold a great promise as the building blocks for future optical devices. In this contribution we investigate the photo-excitation of such structures on semiconductor surfaces using a patterned optical illumination. Using this approach we are able to actively tune localized surface plasmon resonances (LSPRs) both spatially and temporally. Furthermore, the concept of beam-steering for THz waves using photo-generated carriers in semiconductors is explored both theoretically and experimentally.
