中文摘要：

通过数值计算模拟的方法，研究激活性杂质对双重势垒光量子阱滤波器特性的调制。结果表明：无论在外垒层、内垒层还是阱层介质中掺入激活性杂质，光量子阱滤波器各通道均出现光增益放大和带宽变窄现象，而且存在不同光增益极大值和恒定带宽极小值现象。增益倍数和带宽对内垒层掺杂的响应相对外垒层的灵敏，而对多层介质掺杂的响应则比单介质层掺杂的灵敏，但不同的通道对掺杂的响应灵敏度不同。阱层掺入激活杂质时，阱中心通道对各介质层掺杂的响应灵敏度一样，但短波通道对多层介质掺杂响应比单层介质掺杂灵敏，而长波通道则相反；无论是外垒层、内垒层或阱层，对激活掺杂响应均存在相等的极限值。双重势垒光量子阱滤波器对激活性杂质的响应特性为光子晶体设计窄带宽、高品质的光学滤波和高倍数的光学放大器件提供了指导。

英文摘要：

Modulation of activated impurity on filter property of double barrier photonic crystal quantum well is studied by computational simulation method. The results show that no matter which layer the activated impurity is doped in, there appears light gain amplification （with different maximum values） and bandwidth narrowing （with constant minimum values） in filter channels of quantum well. With different sensitive responses in different channels, response of magnification and bandwidth to impurity in inner-barrier layer is more sensitive than the one in outer-barrier layer; similarly, the response to single-layer medium is more sensitive than the one to multilayer. When there is activated impurity in well layer, sensitivities of channel in center well responding to impurity in single- layer and in multilayer medium are the same, but the response sensitivity of shortwave channel to impurity in multilayer is more sensitive than that in single-layer medium. Inversely in long wave channel, no matter which layer activated impurity is doped in, the response sensitivities remain an equivalent extreme value. These properties provide positive guidaace for design of photonic crystals with narrow bandwidths, high-quality optical filtering and high-multinles optical amplifiers.
