Abstract

We present a systematic experimental study of the linear and nonlinear optical properties of silicon-germanium (SiGe) waveguides, conducted on samples of varying cross-sectional dimensions and Ge concentrations. The evolution of the various optical properties for waveguide widths in the range 0.3 to 2 µm and Ge concentrations varying between 10 and 30% is considered. Finally, we comment on the comparative performance of the waveguides, when they are considered for nonlinear applications at telecommunications wavelengths.

摘要

我们展示了一项对硅锗（SiGe）波导的线性和非线性光学特性进行的系统实验研究，该研究是在具有不同横截面尺寸和锗浓度的样品上进行的。考虑了波导宽度在0.3至2微米范围内以及锗浓度在10%至30%之间变化时各种光学特性的演变。最后，我们对这些波导在电信波长下用于非线性应用时的比较性能进行了评论。
