  A compact near-eye visor (NEV) system that can guide light from a display to
the eye could transform augmented reality (AR) technology. Unfortunately,
existing implementations of such an NEV either suffer from small field of view
or chromatic aberrations. See-through quality and bulkiness further make the
overall performance of the visors unsuitable for a seamless user experience.
Metasurfaces are an emerging class of nanophotonic elements that can
dramatically reduce the size of optical elements while enhancing functionality.
In this paper, we present a design of composite metasurfaces for an
ultra-compact NEV. We simulate the performance of a proof-of-principle visor
corrected for chromatic aberrations while providing a large display field of
view (>77{\deg} both horizontally and vertically), good see-through quality
(>70% transmission and less than a wavelength root mean-square (RMS) wavefront
error over the whole visible wavelength range), as needed for an immersive AR
experience.
