摘要

我们报告了减少空腔模态体积并最终增加光-物质耦合强度的物理极限。低于临界长度尺度的极受限光子模式可以引入大的面内波矢量，激发出连续的高动量物质共振。这种激励作为损耗通道，通过涂抹表面电荷的分布来减少场约束，从而限制了可实现的场增强。

Breakdown of Polaritons in Nanophotonic Systems

We report a physical limit for reducing the modal volume of a cavity and ultimately increasing the light-matter coupling strength. Extremely confined photonic mode below a critical length-scale can introduce a large in-plane wave vector and excite a continuum of high momentum matter resonances. This excitations act as loss channels and reduce the field confinement by smearing the distribution of surface charges, thus consequently limiting the achievable field enhancement.
