摘要:

基于平面波展开法,以Ⅲ-Ⅴ族半导体材料AIP、AIAs、AISb和GaP构成二维方形格子光子晶体,并对其光子晶体能态密度特性进行了数值模拟。结果表明,Ⅲ-Ⅴ族半导体材料构成二维方形格子光子晶体具有较好的光子带隙,形成的最大带隙随介电常数差值的增大而增大,f=0.2a时归一化频率达到最大光子带隙,AISb具有较宽的光子禁带。该研究结果为光子晶体器件的研究提供理论依据。

Abstract:

Density states properties of two-dimension square lattice photonic crystals with Ⅲ-ⅤAIP, AIAs, AISb and GaP semiconductor material were calculated by plane wave expansion method (PWM). The results showed that they have wide photonic band gaps. The width of band gap increases gradually with the increasing of permittivity difference and gets the maximum value at f=0.2 in the normalized frequency. The data reveals among these photonic crystals, the one with AISb has the widest band gap. All these results provide theoretic basis for the photonic crystal devices.

Key words: optoelectronics, state density properties, plane wave expansion method, semiconductor material, photonic crystal
