通过平面波展开法，我们对一种特殊的硅介电波导管的声子能带结构与光子能带结构进行了理论研究。为了同时产生光子带隙和声子带隙，在通常的波导管结构中设计了一种周期性的桩型结构。研究发现：在适当的结构参数条件下，一个完整的声子带隙和特定极化对称性的光子带隙可以同时得到。

Phononic and photonic band structures were theoretically investigated in a special silicon dielectric waveguides by plane wave extended method. Periodic stubs were designed along the usual waveguides in favor of creating phononic and photonic band gaps. At appropriate geometrical parameters, a complete phononic gap was obtained together with a photonic gap at given symmetries.
