用于能量量子化光局域化的光学亚原子
Optical meta-atom for localization of light with quantized energy
摘要：
将光限制在空间的一个小区域内的能力在现代科学的许多领域都是至关重要的。在这里，我们提出了一种机制来存储量子化的“位”的光-具有非常精确的能量-在一个开放的核壳等离子体结构（“元原子”）与非线性光学响应。尽管被捕获的光态嵌入在辐射连续体中，但其寿命不受辐射损失的限制。有趣的是，它表明，非线性响应和体积等离子体激元之间的相互作用，使打破基本的互易性限制，并非常有效地耦合外部光源的元原子。入射光脉冲与元原子的碰撞可以用来释放被捕获的辐射“比特”。
英文摘要：
The capacity to confine light into a small region of space is of paramount importance in many areas of modern science. Here, we suggest a mechanism to store a quantized "bit" of light - with a very precise amount of energy - in an open core-shell plasmonic structure ("meta-atom") with a nonlinear optical response. Notwithstanding the trapped light state is embedded in the radiation continuum, its lifetime is not limited by the radiation loss. Interestingly, it is shown that the interplay between the nonlinear response and volume plasmons enables breaking fundamental reciprocity restrictions, and coupling very efficiently an external light source to the meta-atom. The collision of an incident optical pulse with the meta-atom may be used to release the trapped radiation "bit".
