为设计高品质的光学滤波器件，利用传输矩阵法理论，通过数值计算模拟的方法，研究垒、阱层介质折射率对光量子阱滤波带宽的调制机制，结果表明，光量子阱滤波带宽对垒、阱层介质折射率的响应相当灵敏：垒层高折射率介质的折射率越大，光量子阱的滤波带宽越窄；垒、阱层介质的折射率和的比值越大，光量子阱的滤波带宽越窄。光量子阱滤波带宽对介质折射率的响应机制，为提高光子晶体光学滤波器件的品质、性能提供方法依据，同时对光量子阱的理论研究也具有积极的指导意义。

To design high-quality optical filter device, the modulation of medium refractive indexes in barrier and well layer on filter bandwidth of optical quantum well was studied with transfer matrix theory and computational simulation method. The results show that the filter bandwidth is responsive to the refractive indexes of both barrier layer and well layer; filter bandwidth narrows down as the refractive index of high-refractive medium in barrier layer increased; and the greater ratio between refractive index sums of barrier layer and well layer, the narrower filter bandwidth of optical crystal quantum well becomes. The response mechanism of optical crystal quantum well filter bandwidth to medium refractive index can provide theoretical basis to improve the quality and performance of optical filter device and also has positive effects on the theoretical study of optical quantum well.
