Abstract: C23.00004 : Nonlinear light-matter interactions in engineered optical media*
3:30 PM–4:06 PM
(University at Buffalo, The State University of New York)
In this talk, we consider fundamental optical phenomena at the interface of
nonlinear and singular optics in artificial media, including theoretical and
experimental studies of linear and nonlinear light-matter interactions of
vector and singular optical beams in metamaterials. We show 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 (OAM) of
light. We will discuss several approaches to structured light manipulation
on the nanoscale using metal-dielectric, all-dielectric and hyperbolic
metamaterials. These new functionalities, including polarization and OAM
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.
The emergence of metamaterials also has a strong potential to enable a
plethora of novel nonlinear light-matter interactions and even new nonlinear
materials. In particular, nonlinear focusing and defocusing effects are of
paramount importance for manipulation of the minimum focusing spot size of
structured light beams necessary for nanoscale trapping, manipulation, and
fundamental spectroscopic studies. Colloidal suspensions offer as a
promising platform for engineering polarizibilities and realization of large
and tunable nonlinearities. We will present our recent studies of the
phenomenon of spatial modulational instability leading to laser beam
filamentation in an engineered soft-matter nonlinear medium.
Finally, we introduce so-called virtual hyperbolic metamaterials formed by
an array of plasma channels in air as a result of self-focusing of an
intense laser pulse, and show that such structure can be used to manipulate
microwave beams in a free space.
