Title: Flat Optics : from Metalenses to Structured Light
Abstract: Arrays of optically thin, sub-wavelength spaced optical elements (metasurfaces)
have major potential for wavefront shaping through local control of the phase, amplitude
and polarization of light [1]. Flat optics has emerged from this approach [2] with the
goals of replacing refractive lenses in most applications requiring aberrations’
correction [3,4] as well as conventional phase plates used in polarization optics [5] and
last but not least of providing a new path to the creation of structured light [6].
