Plasmonics and Metasurfaces

Plasmonics offer the unique opportunity to mold the flow of light at deep-sub-wavelength scales. Plasmonic systems can exhibit significantly reduced mode volumes, leading to large Purcell enhancement and strong coupling, i.e. strong light/matter interaction, even in the absence of resonant structures. By patterning metallic components into metamaterials, these effects can be further amplified; for instance, metamaterials that exhibit quasi- hyperbolic dispersion can significantly increase the photonic density of states and in turn the coupling of emitters to the modes of the system. We are particularly interested in hybridizing metasurfaces with active optical materials such as quantum emitters and 2D materials.
