Effect of Optical Thickness on Characteristics of Photonic Forbidden Band of 1D Three Element Photonic Crystal
光学厚度对一维三元光子晶体禁带特性的影响

By using the method of optical transfer maxtrix,the characteristics of photonic forbidden band of 1D three element photonic crystal were studied.The investigation results show that the maximal refractive index and the minimal refractive index affect the absolute bandwidth of 1D three element photonic crystal greatly and the middle refractive index affect it slightly,but the middle refractive index affects the relative bandwidth of 1D three element photonic crystal greatly and the maximal refractive index and the minimal refractive index affect it slightly.The absolute bandwidth and the relative bandwidth of 1D three element photonic crystal is largely wider than that of 1D two element photonic crystal.
