摘要
利用传输矩阵方法研究了一维光子晶体的全向反射特性。研究表明,光子晶体的结构参数对全向反射带的产生影响很大。要提高光子晶体的全向反射带带宽,必须增大两种介质的折射率及它们的高低折射率比值,同时使低高折射率层的光学厚度比接近0.85。研究结果对全介质反射器的设计具有指导意义。
The omnidirectional reflection properties of one-dimensional photonic crystals are studied by using the bandgap theory deduced by the transfer matrix method. Investigations show that the constructure parameters affect the omnidirectional reflectivity band of a photonic crystal significantly. In order to increase the omnidirectional reflectivity band, some methods are proposed to increase the refractive index of dielectrics, the ratio of the high and low refractive index, and make the ratio of the optical thickness near to 0.85. The conclusion is helpful for designing a dielectric omnidirectional reflector.
