In order to improve the multi-pixel photon counter (MPPC) high-speed detection and improve the photon-number to distinguish features, we use the gated suppression MPPC, and combine the self-balancing and low-pass filtering technology to suppress the capacitive-spike noise of MPPC down to the thermal noise level, realizing the linear extraction and rapid recovery detection of photogenerated avalanche signal. The experiment result shows that the 200 MHz gated MPPC achieves the effective resolution of 14 photons of the 40 MHz repetition frequency lase with the average detected photon number is up to 6.8 per pulse. Compared with the passive suppression mode, the photon number resolution in the 200 MHz sinusoidal gated mode is obviously improved, which provides a reference for high-speed photon-number resolving detection.
