Stokes polarimetry of near-field polarization of CVVs. a–d Measured two-dimensional maps of near-field Stokes parameters and the comparison with theoretical prediction for devices WG6–8, WG6–10, WG6–12, and WG6–14, respectively. In each case, the four maps show the measured near-field intensity profile of the device with lTC = +4, and the normalized Stokes parameters S1, S2, and S3, respectively. The curves in each case show the comparison between the measured results (dots) sampled from the maps and the corresponding prediction (solid curves) from Eq. (7). For each set of measured data, 288 pixels intersecting with the circle of 80 μm radius along the azimuthal direction (φ) from 0 to 2π are sampled from the corresponding map. For each solid curve, the data are calculated by substituting the transverse-spin state σ from Fig. 3a into Eq. (7)
