Integrated and simultaneous metasurfaces for visible full-Stokes spectropolarimeters

To meet the technical requirements of simultaneously detecting spectral information and full-Stokes polarization, an integrated metasurface device is designed, realizing the measurements of full-Stokes polarization status and multi-wavelength spectrum covering the visible light waveband, from 450 to 650nm. The 460nm, 540nm and 620nm have been selected to test the characteristic performance of the spectropolarimeters. By combining both propagation phase and geometric phase modulation, all Stokes parameters can be precisely measured, including both linear and circular polarization states, while synchronously achieving a multispectral resolution at multiple characteristic wavelengths.
