论文摘要
在过去的几年中，光学纳米安妮纳斯（Nanoantennas）由于其有效限制，定位共鸣的能力而不断引起了兴趣，并在亚波长度尺度上显着增强了电磁场。然而，通过在连续腔中使用适当的光学纳米反滕纳和倾斜结合状态的结合，可以进一步增强这种强烈的限制。在这里，我们提议协同桥接等离激元纳米烷纳和高光学质量因子腔，以数值证明局部强度增强的三个数量级。提议的混合系统为需要高度关键字段的应用铺平了一种新方法，例如光学传感，光学诱捕，非线性光学元件，量子光学元件等。
Over the last few years, optical nanoantennas are continuously attracting interest owing to their ability to efficiently confine, localize resonance, and significantly enhanced electromagnetic fields at subwavelength scale. However, such strong confinement can be further enhanced by using an appropriate combination of optical nanoantenna and Slanted Bound states in the continuum cavities. Here, we propose to synergistically bridge the plasmonic nanoantenna and high optical quality-factor cavities to numerically demonstrate three orders of magnitude local intensity enhancement. The proposed hybrid system paves a new way for applications requiring highly confined fields such as optical sensing, optical trapping, nonlinear optics, quantum optics, etc.
