| 摘 要： | 采用平面波展开法和快速遗传算法优化设计具有大禁带的二维光子晶体.从随机产生的晶体结构开始,在遗传算法中引入占空比控制算符和傅里叶变换数据备份机制,快速搜索到了具有较大绝对禁带的正方晶格光子晶体,其最大完全禁带的相对宽度值为13.25%,并且制备难度较低.

| Abstract: | The plane wave expansion method (PWM) and rapid genetic algorithm (RGA) are used to design two-dimensional photonic crystals with large complete band-gaps.The algorithms evolve from randomly generated photonic crystals and integrate a filling fraction controlling operator and Fourier transform data storage mechanism to run efficiently and effectively.The obtained optimal photonic crystal has a large band gap with a relative width of 13.25% and can be easily fabricated due to large pixel. |

| Keywords: | two-dimensional photonic crystals photonic band gap rapid genetic algorithm plane wave expansion method |
