Abstract

We have developed multifunctional optical beam shapers based on plasmonic metasurfaces. The metasurfaces are composed of subwavelength-spaced polarization- and wavelength-selective optical nanoantennas that allow encoding several beam shapers on a single element. We demonstrate numerically and experimentally beam shapers that can be used to switch between arbitrary beam shapes. We specifically demonstrate switching between one-dimensional Airy and Gaussian beams, Hermite–Gaussian beams of different orders, and two-dimensional Airy and Bessel beams. These beam shapers can be used as integrated optical elements in applications that require more than one laser beam shape.
