通过漏纳米结构的发射极-真空耦合和动力学在光态密度中的作用

Emitter-Vacuum coupling through a leaky nanostructure and the role of dynamics in density of optical states

Kritika Jain, Murugesan Venkatapathi

摘要:

我们打破了传统的分区光学状态到其辐射和非辐射部分。在发射体与仅几纳米尺寸的完全吸收的等离子体纳米颗粒相互作用的情况下,实验观察与当前理论的大分歧现在是显而易见的。波动耗散模型要求非局部行为限制小金属纳米颗粒和近端金属表面。我们指出,广泛使用的技术,以提高光学传感,如表面增强拉曼光谱(SERS),可能是不可行的,但这种效果。从质量上讲,这种量子效应似乎只有在发射光子被附近吸收纳米结构散射的经典概率接近零时才会出现。因此,尽管起源和规模不同,这与黑洞附近产生霍金辐射的量子效应有着有趣的相似之处。

英文摘要:

We show a break down of the conventional partition of optical states into its radiative and non-radiative parts. Large divergence of experimental observations from current theory in the case of emitters interacting with fully absorbing plasmonic nanoparticles only a few nanometers in dimensions, are now evident. A model of fluctuation-dissipation demands non-local behavior from limiting small metal nanoparticles and proximal metal surfaces. We point that widely used techniques to enhance optical sensing such as surface-enhanced-Raman-spectroscopy (SERS), may not have been viable but for this effect. Qualitatively, this quantum effect seems to present itself only when the classical probability of scattering of an emitted photon by a near-by absorbing nanostructure approaches zero. Hence, though different in origin and scale, this has an interesting analogy with quantum effects resulting in Hawking radiation near a black-hole.
