The objective of this project is to investigate fundamental optical phenomena at the interface of two emerging fields of modern optical physics - singular optics and optical metamaterials. Singular optics is a fascinating emerging area of modern optics that considers spin and orbital angular momentum properties of light and brings a new dimension to the science of light and physics in general. Recent developments in the field of metamaterials and transformation optics enable unprecedented control over light propagation and a possibility of engineering space for light propagation, opening a new paradigm in structured light related phenomena in optical physics. We demonstrated that unique optical properties of metamaterials open unlimited prospects to engineer light itself. Thanks to their ability to manipulate both electric and magnetic field components, metamaterials open new degrees of freedom for tailoring complex polarization states and orbital angular momentum of light. We proposed and demonstrated several approaches to structured light manipulation on the nanoscale using metal-dielectric, all-dielectric and hyperbolic metamaterials. These new functionalities, including polarization and orbital angular momentum conversion, beam magnification and de-magnification, and sub-wavelength imaging using novel non-resonant hyperlens are likely to enable a new generation of on-chip or all-fiber structured light applications.
