摘要：
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.
