We report Q-factor enhancement in a one-dimensional (1D) photonic crystal (PC) cavity by embedding electromagnetic-induced-transparency (EIT) planar plasmonic metamaterials in the cavity. Microwave experiments show tenfold Q-factor enhancements, confirming the numerical simulations. More importantly, the Q-factor enhancement is mainly due to both the longitudinal and lateral confinements contributed by the 1D PC cavity and the planar EIT metamaterials, respectively. The combined PC-EIT structure with a prominent cavity figure of merit may find new applications in nonlinear optics, cavity quantum electrodynamics, and low-threshold lasers.
我们报道了通过在一维（1D）光子晶体（PC）腔中嵌入电磁诱导透明（EIT）平面等离子体超材料来提高Q因子。微波实验表明Q因子提高了十倍，证实了数值模拟结果。更重要的是，Q因子的提高主要分别归因于一维PC腔和平面EIT超材料所贡献的纵向和横向限制。具有突出品质因数的PC-EIT组合结构可能在非线性光学、腔量子电动力学和低阈值激光器中找到新的应用。
