Flat Optics : from Metalenses to Structured Light
Seminar by Prof. Federico Capasso, Harvard
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 optics5 and last but not least of providing a new pth to the creation of structured light.
