中文摘要：
通过传输矩阵法理论，研究激活杂质对双重势垒光量子阱滤波器特性的影响，结果表明：介质未掺激活杂质时，双重势垒光量子阱滤波器品质随垒层周期数的增大而提高，同时滤波通道的频率发生位移；内、外垒层或阱层介质分别掺激活杂质时，各共振隧穿模出现高倍光放大现象，且各共振隧穿模的频率位置恒定；随激活介质介电虚部大小的增大光量子阱滤波器品质迅速提高，特别是阱层介质掺杂时品质提高尤为明显，高达8.010×104倍；利用双重势垒光量子阱的阱层或内、外垒层掺杂激活特性，可实现高品质光滤波、光信号放大功能，且为光量子阱的实际设计与应用提供积极指导。
英文摘要：
The effect of active impurity on double barrier photonic quantum well filter was studied by transmission matrix method. The results show that when there was no active impurity in medium, the quality of double barrier quantum well filter increased with the periodicity of barrier layer increase, and the frequency of filtering channel shifted at same time. When there was active impurity in inner-barrier and well layer respectively, the resonant tunneling modes appeared high magnification, but the frequency of tunneling modes were constant. The quality of quantum well filtering increased quickly with the increase of value of imaginary part of dielectric, especially when there was active impurity in well layer, the quality reached 8.010×104. These properties can achieve functions of high-quality optical filtering and optical signal amplification, providing positive guidance for design and application of photonic quantum well.
