为了修正的折射率和吸收的In 1-xGaxAsyP 1-y材料系统的晶格匹配到InP椭圆偏振测量进行。对于第一次一般参数的Tanguy模型确定从这些测量这些材料的组成。利用这些Tanguy参数，考察了透明区和吸收区（包括近、中红外区）的折射率和吸收系数。此外，估计的群速度和色散的这些材料的组成。
For the revision of the refractive indices and absorption of the In1-xGaxAsyP1-y material system lattice matched to InP ellipsometric measurements were carried out. For the first time general parameters for the Tanguy model were determined from these measurements of these material compositions. With the help of these determined Tanguy parameters, the refractive indices and the absorption coefficients were reviewed in transparent and absorption region which includes the near and mid-infrared region. Furthermore, an estimation of the group velocity and the chromatic dispersion is presented for these material compositions.
