Extended Data Fig. 8 |. Performance of the silicon diode (S2387 from Hamamatsu).

Extended Data Fig. 8 |

(a) A photograph of the silicon S2387 diode; (b) Photo and dark current density curves of the Si photodiode. (c) EQE of the Si photodiode. (d) shunting resistance of the photodiode. (e) Dark count rate collected for the photodiode detector for 60 s measured at zero bias. (f) Output of the Si diode measured at zero bias under incident light pulse with photon numbers. The light source for the photon counting performance measurement is a 630 nm picosecond pulse laser from Horiba.
