Abstract
Recent advances in wavefront shaping have enabled new classes of structured light, leading to new phenomena and applications. We review current progress in these areas with focus on meta-optics that exhibit a tunable response at the output by simply changing the properties of incident light; including input polarization, orbital angular momentum, angle of incidence, and/or wavelength. Multifunctional devices of this kind rely on intricate light-matter interaction at the level of meta-atoms which can be difficult to replicate using other wavefront shaping tools. In addition, we present a new class of holograms — dubbed holographic light sheets — for generating 3D structured light and discuss its potential use in AR/VR applications. Lastly, we highlight new directions in generating time-varying optical vortices using dispersion-engineered metasurfaces and discuss its future applications.
