摘要: 利用平面波展开法研究了两种结构的光子晶体(PC)在旋转操作情况下的带隙特性。首先构建了两种结构不同的光子晶体,并比较了这两种光子晶体结构带隙特性的不同。分别讨论了旋转操作对两种结构光子晶体TE模式带隙特性的影响,发现TE模式的带隙受到介质在x-z平面分布情况的影响。根据计算的结果,分析了旋转操作对带隙特性产生影响的原因,并给出了最优化带隙的角度范围。本研究对实验上制作性能优良的光子晶体结构具有比较好的理论指导意义。

Abstract: The plane wave expansion method is used to explore the photonic band-gap characteristics of two kinds of photonic crystal structure under rotation operation. First, constructed two different kinds of photonic crystal structure and compared the difference of the band-gap characteristics of these two kinds of structure. Discussed the effect of the rotation operation on the band gap of two kinds of structure in TE mode respectively, found that the distribution of medium column in x-z plane together influence TE mode band gaps. According to the result of calculation, analyze the reason of the influence on the band gap characteristics, and give the angle range of the optimum band gap. It has better theoretical guiding significance on producing photonic crystal of good performance.

Key words: optoelectronics, photonic crystal, plane wave expansion method, angle of rotation
