光接收器件新物料验证中耦合参数的设定

Setting of coupling parameters in the verification of new materials for optical receiving components

二极管跨阻放大器(PIN-TIA)具有传输距离长、电压成本低、噪声低等优点,广泛应用于光电传输系统。灵敏度是光电探测器乃至光通讯系统的关键指标之一,其测量是统计误码率,耗时较长,批量生产中多用输出响应电压/输出响应电流代替灵敏度进行耦合。分析二极管跨阻放大器光电探测器内部各部件工作原理,验证改变产品原有物料后耦合参数是否需要调整,总结完整的新品验证中参数的设定方法,指导生产过程设定合适的响应度调试参数,并通过批量生产验证。

Diode transimpedance amplifier(PIN-TIA)has the advantages of long transmission distance,low voltage cost,and low noise,and is widely used in optoelectronic transmission systems.Sensitivity is one of the key indicators of photodetectors and even optical communication systems,and its measurement is based on statistical error rate,which takes a long time.In batch production,response voltage/response current is often used instead of sensitivity for coupling.This thesis analyzes the working principle of various components inside the diode cross resistance amplifier photodetector,verifies whether the coupling parameters need to be adjusted after changing the original material of the product,summarizes the complete parameter setting method in new product validation,guides the production process to set appropriate responsiveness debugging parameters,and verifies the new materials through batch production.
