摘要
设计了一维三元对称光子晶体结构,用传输矩阵法对其偏振滤波特性进行了研究。结果表明,入射角、介质厚度增大,两偏振波的禁带和共振模的分离度变大。周期数目N增大,对两偏振波的共振模的分离度影响最明显。晶体结构对称度的改变,对两种波的禁带和共振模的分离度影响不大。
A kind of one-dimensional three element photonic crystal with symmetrical structure has been designed.The polarization filtering properties have been studied by using the transfer matrix method.It is found that the separation degree of band gap and resonance mode of two polarized waves increase with the increase of the incident angle and medium thickness,and the increase of the period number N has obvious influence on the separation degree of the two polarized waves,while the change of the symmetry degree of the crystal structure has little effect on the separation degree of band gap and resonant mode of the two waves.
