16 Supplementary Figure 9. Simulation of Photocurrent. Supplementary Figure 9 Simulated current flow distributions for four direct Stokes photodetectors. The six rows represent different polarisation states: x-polarisation, y-polarisation, 45°, –45°, right-circular polarisation (RCP), and left-circular polarisation (LCP). Each column corresponds to one structure optimised for a specific Stokes parameter (S₀–S₃), showing selective current response under different polarisations.
