Abstract

We report a novel guided-wave resonator that supports multiple bands of electromagnetically induced transparency (EIT). The platform for the spatial and spectral interference is obtained by a microstrip transmission line loaded with proximity-coupled open-circuited stubs. We show experimentally that with two microstrip open stubs, a complete destructive interference takes place leading to a single EIT band with near-unity transmission efficiency. More interestingly, the addition of a third stub results in a supplementary EIT band with a Q-factor of 147 and an effective group refractive index of 530. With the open-stub configuration, the EIT phase response can be dynamically controlled by varying the capacitance between the adjacent stubs without breaking the transmission path of the underlying electromagnetic waves. Therefore, the proposed structure is well suited for buffering and tunable phase modulation applications. Since the proposed structures are compact and fully planar, we anticipate seamless integration with low-profile high frequency electronics.

摘要

我们报告了一种新型导波谐振器,它支持多个电磁感应透明(EIT)频段。通过微带传输线加载接近耦合开路短截线获得了空间和光谱干涉的平台。我们通过实验表明,使用两个微带开路短截线,会发生完全的相消干涉,导致具有近 100%传输效率的单个 EIT 带。更有趣的是,添加第三个短截线会导致具有 Q 因子为 147 和有效群折射率为 530 的补充 EIT 带。通过开路短截线配置,可以通过改变相邻短截线之间的电容来动态控制 EIT 相响应,而不会中断基础电磁波的传输路径。因此,所提出的结构非常适合缓冲和可调谐的相位调制应用。由于所提出的结构紧凑且完全平面,我们预计可以与低轮廓高频电子设备无缝集成。
