摘　　要：用传输矩阵的方法研究了一维三元光子晶体带增益介质微腔的传输特性,结果显示透射谱有模式竞争的特性。发现透射主峰的中心波长和ZnO增益介质层厚度互相匹配。在其他参数合适的情况下,改变ZnO增益介质层厚度,透射主峰的中心波长也相应改变。另外,增大光子晶体介质层数目或是增大泵浦光强度,模式竞争现象更加明显。We present the characteristics of mode competition with gain medium in the micro-cavity of one-demensional ternary photonic crystal with transfer matrix method.From the results,we know that the transmission spectra have the characteristics of mode competition.And then,we also know the central wavelength of the peak transmission and the thickness of the ZnO gain medium are matching.In the case of other appropriate parameters,if we change the thickness of the ZnO gain medium,the central wavelength of the peak transmission will also be changed.In addition,we increase the number of the dielectric layer of photonic crystal or the intensity of pump light,the mode competition will be more pronounced.
