论文摘要
通过大量研究了通过路径干扰效应（即FANO共振）控制纳米结构的非线性响应。在此类研究中，频率转换过程发生在热点附近。在这里，我们研究了发生频率转换过程\ textit {沿非线性晶体}的情况的情况。金属纳米粒子 - 量子发射极二聚体通过引入干扰转换路径来控制整个晶体体内的下转换过程。二聚体的行为作为互动中心。我们表明，由于定位效应，还可以增强2个数量级的增强。也就是说，由于现场定位，该因素乘以增强。
Control of nonlinear response of nanostructures via path interference effects, i.e., Fano resonances, has been studied extensively. In such studies, a frequency conversion process takes place near a hot spot. Here, we study the case where the frequency conversion process takes place \textit{along the body of a nonlinear crystal}. Metal nanoparticle-quantum emitter dimers control the down-conversion process, taking place throughout the crystal body, via introducing interfering conversion paths. Dimers behave as interaction centers. We show that a 2 orders of magnitude enhancement is possible, on top of the enhancement due to localization effects. That is, this factor multiplies the enhancement taking place due to the field localization.
