Title:
Time-Resolved Detection of Photon-Surface-Plasmon Coupling at Single Quanta Level
Abstract:
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, the time
resolved study of the interaction is invaluable. We have demonstrated the time
resolved detection of photon-surface-plasmon coupling by exploiting single and
entangled photons with long coherence time to excite single optical plasmons. Using
the new technique, we examined the nonclassical correlation between the single
photons and single optical plasmons in such systems with the time-resolved Cauchy
Schwarz inequality. We also realized 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.
