This project focuses on the design, modeling, fabrication, and optical characterization of metallo-dielectric nanostructures in which light is manipulated at a deep subwavelength scale to achieve tailored electromagnetic responses not found in nature and which can in turn be leveraged to implement novel photonic devices for imaging, sensing, and metrology. Structures under current study include negative-index¹ and hyperbolic² metamaterials operating in the visible and ultraviolet, as well as passive and active plasmonic waveguides and cavity resonators with high quality factors and index-switching contrast. The optomechanical properties of metamaterial surfaces, in particular their anomalous response to radiation pressure, also represents topic of significant interest. The research has a strong experimental emphasis, leveraging a variety of advanced nanofabrication techniques available in a fully-equipped clean room, such as thin-film deposition, electron-beam lithography and focused-ion-beam machining, as well as state-of-the-art optical measurements using continuous wave and pulsed lasers, inverted and near-field microscopes, heterodyne interferometers, and grating spectrometers.
