45、电子被冲击离子化后，产生雪崩倍增效应，电子和空穴不断产生。 这种元件可以用作 0.8m 范围的光纤通信的受光装置和光磁盘的受光期间还，能够 有效地处理微弱光线的问题，当量子效率为 68%以上时，可得到大于 300MHz 的高速响 应。工作电压小于 180V 时，则暗电流仅为 0.3nA。采用锗的 APD 所使用的波长范围接 近于 1m,由于它专用于光纤通信，所以其响应速度高达 600MHz 以上，偏压 30V 以下时， 可获得高于 55%的量子效率。暗电流很大，为 0.5uA 左右。GCAPD-B 型 APD 雪崩光 电二极管综合实验仪主要研究 APD 光电二极管的基本特性，如光电流、暗电流、

46、光照 特性、光谱特性、伏安特性及时间相应特性等，以及这种光敏器件与其它光电器件的应 用差别。 二、实验仪说明二、实验仪说明 1 1、电子电路部分结构分布、电子电路部分结构分布 电子电路部分功能说明 （1）电压表：独立电压表，可切换三档，200mV，2V，20V，通过拨段开关进行调节， 白色所指示的位置即为所对应的档位。 “+” “-”分别对应电压表的“正” “负”输入极。 （2）电流表：独立电流表，可切换四档，200uA，2mA，20mA，200mA 通过拨段开关进 行调节，白色所指示的位置即为所对应的档位。 “+” “-”分别对应电压表的“正” “负”输入极。 （3）照度计电源：红色为照度计
