摘要: 利用平面波展开法对十重准周期光子晶体(QPC)的带隙特性进行了研究。讨论了十重QPC的第一带隙宽度随介电常数对比度、介质柱填充因子的变化规律,发现带隙宽度和介电常数存在线性关系,并且存在最佳的填充因子。通过比较TE和TM模式的带隙,发现TM偏振模式下的带隙更宽。并比较了十重QPC与八重QPC的带隙特性,发现十重准晶光子晶体更容易产生带隙。

Abstract: The photonic band-gap characteristics of ten-fold QPC are explored by using plane wave expansion method. The variation of the first band-gap is discussed with the dielectric constant and filling factor. It is found that there exists a linear relationship between the band-gap width and dielectric constant and there is an optimal filling factor. By comparing the band-gap of TE and TM mode, we find that TM mode has a wider band. Furthermore, a comparison between ten-fold and eight-fold QPC proves that it is easier to produce band-gap for the ten-fold QPC.

Key words: photonic crystals, ten-fold photonic quasicrystal, plane wave expansion method, band gap characteristics
