在适当选择结构参数基础上,通过传输矩阵法计算模拟光子晶体(AB)m(CD)n(BA)m结构模型的透射谱,当光子晶体(CD)n的三个导带分别处于光子晶体(AB)m(AB)m相邻的三个禁带中时,构成光子晶体三量子阱结构,在光量子阱透射谱的归一化频率1.0(ωa/2πc),2.0(ωa/2πc)和3.0(ωa/2πc)三处周围,分布着三套具有规律的局域共振峰,出现明显的量子化效应,且三套透过峰数目都可以通过光子晶体(CD)n的重复周期数n来调节,这一现象可用于设计可调性多通道滤波器。
Based on the appropriate choice of the structural parameters, the transmission spectra of the simulated photonic crystal (AB) m (CD) n (BA) m are calculated by the transfer matrix method. When the three conduction bands of the photonic crystal (CD) n are in the photonic crystal (Ωa / 2πc), 2.0 (ωa / 2πc), and the normalized frequency of the transmission spectrum of the photon quantum well are calculated by using three quantum well structures adjacent to the (AB) m (AB) 3.0 (ωa / 2πc) around the distribution of three sets of regular local formant, a clear quantum effect, and the number of three sets of transmission through the photonic crystal (CD) n repetition period number n To adjust, this phenomenon can be used to design adjustable multi-channel filter.
