摘要: 本文采用砷化镓(GaAs)六边形散射元构建的光子晶体，分别计算了两种无缺陷结构的色散曲线，得到其群折射率、群速度、带宽和归一化带宽积。研究表明：对于完美结构：上下底面相同r = 0.05 μm时，归一化带宽积为0.262；上下底面不同r = 0.05 μm时，归一化带宽积为0.250，两种结构都有很好的慢光效应。
Abstract: The dispersion curves of two defect-free structures are calculated by photonic crystal by gallium arsenide (GaAs) hexagonal scatterers in this paper, and the group refractive index, group velocity, bandwidth and normalized band width product are obtained, respectively. The results show that for the perfect structure, when the upper and lower bottom surface is the same and r = 0.05 μm, the normalized band width product is 0.262, and when the upper and lower bottom surface is different and r = 0.05 μm, the normalized band width product is 0.250, so both structures have good slow light effect.
