为了得到给定波长为通带或禁带的光子晶体，采用光学传输矩阵方法，模拟研究了由光子带隙结构如何得到相应的光子晶体结构。通过优化计算得到了指定波长带隙结构的光子晶体。结果表明，光学传输矩阵法完全能得到给定波长为通带或禁带的光子晶体。这一结果有助于光子晶体的广泛应用。

For photonic crystals whose certain wavelength is forbid band or permit band,how to gain the photonic crystals structure from the photonic band gap structure was studied by means of transfer matrix method. Simulation result was obtained about the photonic crystals of the certain wavelength band gap. The result shows the method can completely gain the photonic crystals whose the certain wavelength is forbid band or permit band. The result conduces to the extensive application of the photonic crystals.
