摘要

采用优化算法设计了光线下大绝对带隙的二维六边形晶格光子晶体。通过优化圆孔在晶胞中的位置和半径，提出了考虑不同圆孔数的四种设计方案。遗传算法最终得到了在中频0.3712(2πc/a)处绝对共带隙为0.0796(2πc/a)的光子晶体。

Genetic algorithm for band gap optimization under light line in two-dimensional photonic crystals

An optimization algorithm is used to design two-dimensional photonic crystals in hexagonal lattice for large absolute band gaps under light line. By optimizing the location and radius of circular hole in the unit cell, we present four designs considering different circular hole numbers. The genetic algorithm finally yielded a photonic crystal with an absolute common band gap of 0.0796(2πc/a) at the mid-frequency of 0.3712(2πc/a).
