摘要
采用传输矩阵法对一维光子晶体的带隙结构进行了研究。当介质层的宽度发生改变时,带隙也随之相应地发生变化。数值分析结果表明:通过对介质层不同厚度的组合可获得连续且更大的带隙,运用此方法可在不改变光子晶体材料总体介质厚度的情况下获得理想的滤波效果。
The band gap structure of one-dimensional photonic crystals is investigated using the transfer matrix method. When the width of medium layer is changed, the band gap will be changed accordingly. Numerical analysis results show that continuous and larger band gaps can be obtained by combination of different thickness of medium layers. By using this method, the ideal filtering effect can be obtained without changing the total medium thickness of photonic crystal materials.
