Weak Exciton-Photon Coupling of PbS Nanocrystals in Air-Slot Mode-Gap Si Photonic Crystal Nanocavities in the Near-Infrared
We demonstrate micro-photoluminescence measurements of PbS nanocrystals coupled to air-slot mode-gap photonic crystal nanocavities with Q~15,000 and V[subscript eff] ~0.02 (λ/n[subscript air])³. The ultrahigh Q/V ratios are critical for applications in cavity QED, nonlinear optics and sensing.
