Fig. 5: Full-Stokes polarimetric measurements.
a Schematics and optical microscope image of metasurface design to fully characterize the polarization state (SoP) of the incident light. The required units are marked by P0 through P6. The two additional units labeled \({\mathrm{P}}_5^\prime\) and \({\mathrm{P}}_6^\prime\) provide the capability to identify Stokes parameters at a different working wavelength. b Comparison of the SoP obtained using a conventional polarization analysis method (black circles) and our device (red solid lines), using polar plots and polarization ellipses, at an operational wavelength of 1.45 µm. c Stokes parameters (S0–S3) extracted for eight different random input SoPs, using a polarization analyzer (black circles) and our device (red circles)
