论文摘要
由于基本利益和潜在的应用，非经典光线和表面等离子体的相互作用引起了人们的关注。为了更多地了解光子表面 - 平面耦合的量子性质，相互作用的时间分辨检测是无价的。在这里，我们通过利用单个和纠缠的光子（较长的连贯时间）来激发单个光学等离子体来证明光子表面 - 平面耦合的时间分辨检测。我们使用时间分辨的Cauchy-Schwarz不等式检查了此类系统中单光子和单个光学等离子体之间的非经典相关性。我们还通过操纵入射单光子的波形来实现具有可编程时间波袋的单个光学等离子体。单个光学等离子体的时间分辨检测和相干控制为研究和控制纳米级的光 - 物质相互作用提供了新的机会。
The interplay of nonclassical light and surface plasmons has attracted considerable attention due to fundamental interests and potential applications. To gain more insight into the quantum nature of the photon-surface-plasmon coupling, time-resolved detection of the interaction is invaluable. Here we demonstrate the time-resolved detection of photon-surface-plasmon coupling by exploiting single and entangled photons with long coherence time to excite single optical plasmons. We examine the nonclassical correlation between the single photons and single optical plasmons in such systems using the time-resolved Cauchy-Schwarz inequality. We also realize single optical plasmons with programmable temporal wavepacket by manipulating the waveform of incident single photons. The time-resolved detection and coherent control of single optical plasmons offer new opportunities to study and control the light-matter interaction at the nanoscale.
