中文摘要：

在这份报纸，我们在场两倍平衡微分配置，从一样的晶片的二根邻近的单个光子雪崩二极管( SPAD )作为第一在被设置的一个创新方法平衡结构，并且从首先平衡的阶段的产量信号由稀释的门被减去开车作为第二个平衡阶段发信号。紧缩的设备被凉下来到要描绘的 236 K。以 400 MHz 的门重复率和 10 MHz 的 1 550 nm 激光重复率， 13.5% 罐头的最大的光子察觉效率被完成。黑暗计数率是大约 10 < 啜 class= “ a-plus-plus ” > 4 ns < 啜 class= “ a-plus-plus ” > 在 10% 的光子察觉效率的 1 。afterpulsing 概率指数地与时间减少。这种配置是有效的处于高速度 gating 率区别极端弱的雪崩信号，这被显示出。

英文摘要：

In this paper, we present an innovative method of double balanced differential configuration, in which two adjacent single photon avalanche diodes （SPADs） from the same wafer are configured as the first balanced structure, and the output signal from the first balanced stage is subtracted by the attenuated gate driving signal as the second balanced stage. The compact device is cooled down to 236 K to be characterized. At a gate repetition rate of 400 MHz and a 1 550 nm laser repetition rate of 10 MHz, the maximum photon detection efficiency of 13.5% can be achieved. The dark count rate is about 10^-4 ns^-1 at photon detection efficiency of 10%. The afterpulsing probability decreases with time exponentially. It is shown that this configuration is effective to discriminate the ultra-weak avalanche signal in high speed gating rates.
