High numerical aperture all-dielectric metasurface micro-lenses
conference paper
In this paper, the design principles and the sensitivity analysis needed for the realization of a high numerical aperture metasurface micro-lens are presented. The metasurface micro-lens is realized defining a surface with spatially-variant dielectric resonators embedded in a dielectric bulk. The designed micro-lens achieves a numerical aperture of 0.86 at the visible wavelength of 635 nm with miniaturized dimensions (total active area on the order of tens of square micrometers). These features makes the design extremely interesting for integrated photonic applications.
