摘要
采用角度扫描衰减全反射(ATR)技术,对银金属膜包覆的DR-1/PMMA型有机聚合物波导的色散特性进行了实验研究,从各波长下衰减全反射共振吸收峰的位置和半宽度确定了波导相应模式的传播常数,实验结果与理论计算符合较好,说明银膜介电常数的虚部可作为微扰小量处理。
The dispersion characteristics of a silver metal clad organics polymer (DR 1/PMMA) waveguide are experimentaly studied by the angle scanning ATR technology. The mode propagation constants of the waveguide are deteminated from the positions and the half width of the ATR resonant absorption dip, and the experimental results are consistent with the theoretical calculated values.
