In this paper, we propose and demonstrate numerically a pixelated component for full Stokes polarization imaging by integrating linear polarizers and circular polarizers on a single silicon chip working in near infrared band (~1.6μm). The micro linear polarizers collect linear polarizing information from different orientations while the circular polarizers collect left-handed or right-handed circular polarization information such that full Stokes polarization imaging can be implemented on a single chip in real time. Numerical results show that the extinction ratio and TM transmission of linearly polarization can reach 45dB and 78%, respectively, with a linear metallic grating of period 300nm, and the dichroism of left-handed and right-handed circular polarization can reach 55% with a plasmonic chiral structure that is compatible with linear gratings in terms of structure and fabrication. The proposed structure is of significance in real-time full Stokes polarization imaging.
