论文摘要
最近证明，在耦合到二维电子气体的深层差距谐振器中，耦合到传播等离子可以导致能量泄漏并防止形成偏光谐振。类似于Landau阻尼的过程限制了可实现的场限制，从而限制了光耦合强度的价值。在这项工作中，我们展示了如何使用等离子体亚波长反射器在等离子分散体中创建人造能量挡块，限制它们并使偏振谐振的恢复。使用这种方法，我们证明了frime-marmater耦合比为ω/ω= 0.35，在真空中使用单个量子孔，隙大小为λ/2400。
It was recently demonstrated that, in deep subwavelength gap resonators coupled to two-dimensional electron gases, coupling to propagating plasmons can lead to energy leakage and prevent the formation of polaritonic resonances. This process, akin to Landau damping, limits the achievable field confinement and thus the value of light-matter coupling strength. In this work, we show how plasmonic subwavelength reflectors can be used to create an artificial energy stopband in the plasmon dispersion, confining them and enabling the recovery of the polaritonic resonances. Using this approach we demonstrate a normalized light-matter coupling ratio of Ω/ω = 0.35 employing a single quantum well with a gap size of λ/2400 in vacuum.
