Fig. 4: Polarization selective operation of SOS meta-optics.

a Symmetry-breaking of the scatterer, introducing another degree of freedom, Y. b Phase response for scatterer with rectangular footprint at a wavelength of 550 nm for y-polarized light. c Illustration of a single aperture meta-optic with two different phase profiles implemented for orthogonal polarizations. The phase mask implemented for x-polarized light is shown on a blue colorscale. The phase mask implemented for y-polarized light is shown on a red colorscale. d Direct measurement of the focal spots on a sensor for polarizations correspond to 0°, 45°, and 90°. e Contrast in the two focal spots of the polarization multiplexed meta-optic
