AI 中文摘要
我们通过实验和理论证明了一种基于辐射损耗介导耦合来组合纳米光子模式的通用机制。对于两个模式的情况,该机制导致一种类BIC现象,其特征是出现高品质因子的亚辐射模式。在双金属贴片天线阵列的中红外范围内通过实验观察到了这种模式,其中辐射损耗率由系统几何结构控制。由于该机制与相互作用模式的具体性质或数量无关,可用于组合物理上不同的谐振结构,为基于共振的纳米光子器件开辟了新机会。
英文摘要
We demonstrate, experimentally and theoretically, a universal mechanism for combining nanophotonic modes relying on radiative-loss-mediated couplings. For the case of two modes this mechanism leads to a BIC-type phenomenon characterized by the emergence of a high-quality factor subradiant mode. This mode is experimentally observed in the mid-infrared range, in arrays of double-metal patch antennas where the radiation loss rates are controlled by the geometry of the system. As the mechanism described here is independent of the specific nature or number of the interacting modes, it can be used to combine physically different resonating structures, without requiring fine symmetry tuning or specific modal configurations, opening new opportunities for resonance-based nanophotonic devices.
