论文摘要
在单个微台面中，嵌入的活性发射器本质上会影响微视孔的空腔模式，从而导致琐碎的对称反向散射和低的可控性。在这里，我们通过优化腔尺寸，提出对反向散射方向的宏观控制。用两个强耦合的微型风险确认每个单个微型风险的正面和负反向散射方向的特征。此外，在两个微型爆炸的共振下达到了恶魔般的点，这与考虑反向散射方向的理论计算非常吻合。主动光学结构中的恶魔点铺平了一种用量子光子网络中的几何阶段实现量子信息处理的方法。
In single microdisks, embedded active emitters intrinsically affect the cavity mode of microdisks, which results in a trivial symmetric backscattering and a low controllability. Here we propose a macroscopical control of the backscattering direction by optimizing the cavity size. The signature of positive and negative backscattering directions in each single microdisk is confirmed with two strongly coupled microdisks. Furthermore, the diabolical points are achieved at the resonance of two microdisks, which agrees well with the theoretical calculations considering backscattering directions. The diabolical points in active optical structures pave a way to implement quantum information processing with geometric phase in quantum photonic networks.
