From: High-performance polarization management devices based on thin-film lithium niobate
a The schematics of the device for the arbitrary SOP generation. Inset: the position of SOP on the Poincaré sphere when changing θ (blue line) or φ (red line) of the electro-optic (EO) phase shifters. b The measured Stokes vectors as a function of time when applying two triangle wave signals with frequencies of 200 Hz and 10 kHz to θ and φ EO phase shifter, respectively. c The measured Stokes vectors on the Poincaré sphere of the output from the device, indicating a polarization extinction ratio (PER) of 22.8 dB. d The schematics of a multi-stage device with an improved PER. e The measured Stokes vectors of the output from the multi-stage device, indicating a PER of 41.9 dB
