a The experiment setup used for characterizing the fast polarization measuring device. Inset: the microscope image of a flip-chip bonded photodetector (PD). According to the optical intensities recorded by the PD, the input state of polarization (SOP) can be reconstructed. b The measured results (blue line) from the device and the corresponding input polarization states (orange line). c SOP deviation between the input SOP and the measured one
