提出一种新颖的方法用于测量电吸收调制器(electroabsorption modulator,EAM)各种因素造成的插入损耗.此方法仅需要测量波长相关的光电流(Iph-λ)和光透过功率(P-λ)的数据,通过最小二乘法拟合出结果.理论分析表明此方法较精确,实验表明测试结果与理论拟合结果自洽得很好.
A novel method to ascertain diversified factors contributing to total insertion loss in an electroabsorption modulator is presented. Only the measurement of photocurrent and power transmission vs. wavelength is needed. It' s an accurate method, as shown by both theory analysis and experimental results.
