Nonlinear Optical Metasurfaces

The nominee was an invited speaker for the 2020 March meeting but had their talk canceled. I am resubmitting the nomination so it can be considered for the 2021 meeting. Their 2020 abstract is below:
Nonlinear optics is a decades-old, well-established discipline that normally relies on macroscopic media and propagation lengths that are much longer than the wavelength. Recent progress in artificially structured materials has enabled a resurgence of this field into new directions and phenomena. Examples are increased efficiencies using materials that were not useful for bulk nonlinear optics and complete relaxation of phase matching conditions. In this talk I will cover some of these new developments in nonlinear optical metasurfaces and hybrid nonlinear metasurfaces that include semiconductor quantum wells.
