Mid-infrared polarization-sensitive photodetectors are desired for several applications, such as chemical analysis and biomedical diagnosis. Here, the authors report on-chip polarimeters based on the combination of plasmonic chiral metamaterials and 2D thermoelectric materials, showing tunable full-Stokes detection of linearly and circularly polarized light at room temperature.
