| 摘 要： | 提出了折射率和层厚分别递增或递减的准周期一维光子晶体结构,并用传输矩阵计算了此类准周期光子晶体的透射谱,其光子带隙均相对于周期性光子晶体带隙产生了移动。当折射率递变时,移动方向与递变符号有关。当层厚递变时,光子带隙均向长波方向移动。光子带隙移动量的大小随周期数的增加而增加。

| Abstract: | A quasi-periodic one-dimensional photonic crystal structure was proposed,in which the refractive index and the layer thickness respectively increased or decreased.By using the Transfer Matrix Method the transmission spectra of such a quasi-periodic photonic crystal was calculated numerically,of which the photonic band-gap moved away from the position of periodical photonic crystal band-gap.When the refractive index changed the moving direction,it relied on the sign of change.When the thickness changed the photonic band-gap always moved in the direction of long-wavelength. The magnitude of photonic band-gap shifting increased with the number of periods increasing. |
