摘　　要：利用传输矩阵法,给出一维函数型组合结构光子晶体的匹配矩阵和传输矩阵,在此基础上研究一维函数光子晶体的界面态,并研究折射率端点值、介质厚度和入射角对界面态位置的影响.结果表明:在总阻抗虚部为0的位置出现界面态;对函数介质,当折射率的起始端点值增加时,界面态位置随带隙红移;当折射率的终点值增加时,界面态位置随带隙红移;当介质厚度增大时,界面态位置随带隙红移;当入射角增加时,界面态位置随带隙蓝移.因此函数型光子晶体可调节界面态的位置.By using the transmission matrix method,the matching matrix and transmission matrix of one-dimensional functional composite structure photonic crystal were given.On this basis,we studied the interface state of one-dimensional functional photonic crystals,and studied the influence of refractive index endpoint value,thickness of medium and incident angle on the position of interface state.The results show that interface state appears at the position where the imaginary part of the total impedance is 0.For functional media,when the initial endpoint value of refractive index increases,the position of interface state shifts red with the band gap,when the endpoint value of refractive index increases,the position of interface state shifts red with the band gap.When the thickness of the medium increases,the position of the interface state shifts red with the band gap.When the incidence angle increases,the position of interface state shifts blue with the band gap.Therefore,the position of interface states can be adjusted by functional photonic crystals.
