基于传输矩阵法,数值研究了掺杂一维光子晶体带隙特征。研究表明：一维掺杂光晶体禁带中心位置出现一个极窄的导带,当杂质前半部分层数给定时,后半部分总存在一个层数,使得禁带中心导带的深度达到最大,在此基础上通过改变基本层厚度发现,禁带中心的导带深度仍然最大,我们可以通过改变基本层厚度厚度,让特定波长的光顺利通过。
基于傳輸矩陣法,數值研究瞭摻雜一維光子晶體帶隙特徵。研究錶明：一維摻雜光晶體禁帶中心位置齣現一箇極窄的導帶,噹雜質前半部分層數給定時,後半部分總存在一箇層數,使得禁帶中心導帶的深度達到最大,在此基礎上通過改變基本層厚度髮現,禁帶中心的導帶深度仍然最大,我們可以通過改變基本層厚度厚度,讓特定波長的光順利通過。

The properties of band - gap of one - dimensional doped photonic crystal are studied by using numerical- ly method based on the transfer matrix method. The result shows that a narrow conduction band appears in the cen- tre of forbidden band in one - dimensional doped photonic crystal. The depth of conduction band appears in the centre of forbidden band has a maximum, which was caused by the number of layers of the second half of impurity where the first one was fixed. It shows that the forbidden band center＇s conduction band depth was still biggest by means of changing basic level thickness.
