Metasurfaces based on sub-wavelength patterning have major potential for realizing arbitrary control of the wavefront of the diffracted light by achieving local control of the phase, amplitude and polarization. High performance metalenses in the visible and applications to ultracompact spectrometers and chiral imaging will be discussed along with vortex plates, spin to orbital angular momentum converters, axicons which create arbitrary Bessel beams, and chiral holograms.
