利用Order-N算法及超晶格技术讨论了位置无序及尺寸无序对石墨点阵柱状光子晶体光子带隙的影响·计算结果表明,对于电场偏振模,光子带隙对尺寸无序更加敏感·在此基础上,利用三维时域有限差分方法进一步讨论了无序光子晶体对石墨点阵柱状中心柱光子晶体GaN发光二极管模型光输出效率的影响·计算结果表明,无序对这种光子晶体发光二极管模型光输出效率的影响较小,且这种影响也是随机的
The effect of disordered position and size disorder on the photonic bandgap of graphite lattice columnar photonic crystals is discussed by using Order-N and superlattice techniques. The calculated results show that the photonic bandgap is more sensitive to the disorder of size for the electric field polarization mode · Based on this, the influence of disordered photonic crystals on the light output efficiency of GaN light-emitting diode model was also discussed by using the FDTD method. The calculated results show that the disordered photonic crystals Light-emitting diode model light output efficiency of less affected, and this effect is random
