a Schematic diagram of optical setup for the CPL sensing and imaging measurement. b, c Polar plots of the polarization-dependent response current of 1D-S/SWNTs and 1D-R/SWNTs based PAS, respectively. d Transient EPSC of PAS device in response to single LCP and RCP (395 nm, 10 \(\mu\)W cm−2) pulses. e EPSC induced by a pair of LCP/RCP spikes (395 nm, 10 \(\mu\)W cm−2) with the interval of 1 s. f Variation of PPF index with the increase of excitatory stimuli interval. g EPSC of 1D-S based PAS excited by consecutive LCP and RCP spikes.
