Strongly Coupled Quantum-Dot Plasmonic-Nanoparticle Assemblies for Low-Power Optical Nonlinearities

摘要

We have demonstrated induced transparency (Fano interference) and strong coupling (Rabi splitting) between a single colloidal quantum dot and a plasmonic metal nano-cavity at room temperature. These structures have the potential to serve as ultrafast, low-power optical modulators on the nanoscale.
