我们报道了在单胞中含有两个不同棒原子的光子晶体，它们的相对构型被仔细地调节以优化光子带结构（二维二元复合光子晶体）。通过在单胞中的适当位置引入第二个原子，可以调谐任意能带之间的光子带隙。特别是，通过精心寻找第二个原子的最佳位置，我们可以确定使光子带隙最大化的原子构型。
We report photonic crystals with two different rod atoms in the unit cell, the relative configuration of which is carefully regulated to optimize the photonic band structures (two-dimensional binary-compound photonic crystals). The photonic band gaps between any bands are found to be tuned by introducing the second atom at an appropriate position in the unit cell. In particular, by elaborately searching for the optimal position of the second atom, we can determine the atomic configurations that maximize the photonic band gaps.
