Guiding properties of nanoscale metallic wire waveguides embedded in a semiconductor are discussed. By performing eigenmode numerical simulations of the waveguide and continually varying the geometrical cross-section parameters, we have obtained comprehensive mode characteristics, such as the effective refractive index, effective mode area, and propagation length, that provide full guided mode description. This allows us to gain insight into possible waveguide applications using the figures of merit. Amplification and polarization manipulation of a plasmonic signal in such a waveguide have also been considered.
讨论了嵌入半导体中的纳米尺度金属线波导的引导特性。通过对波导进行本征模数值模拟，并不断改变几何横截面参数，我们获得了全面的模式特性，如有效折射率、有效模面积和传播长度，这些特性提供了完整的导模描述。这使我们能够利用这些优值来深入了解可能的波导应用。还考虑了在这种波导中对等离子体信号进行放大和偏振操纵。
