Figure | Demonstration of all-in-one APCD metasurfaces acting on unpolarized incident light

Caption

a, Experimental setup for the degree of polarization (DoP) measurement of transmitted light from APCD metasurfaces illuminated by an unpolarized LED source. b-d, Measured main axis angle ψ, ellipticity angle χ and DoPs of the transmitted beams through the designed (b) elliptical, (c) linear and (d) circular dichroism metasurfaces. The green polarization ellipses represent polarization states derived from measured Stokes parameters at 633 nm, which are consistent with the simulated states (red arrows).
