We demonstrated a strong optomechanical coupling in a high-quality factor (Q) air-slot mode-gap photonic crystal cavity with ultrasmall mode volume, with a coupling length L∼2.9µm. Optomechanical coupling lengths with different slot gaps and lengths were also compared.
We present experimental analysis of weak coupling for monolayer lead sulfide quantum dots coupled to silicon photonic crystal cavities between 4 K and room temperature, as well as power-saturation measurements of dots at 4 K.
We describe a scalable nanocavity array, with single quantum dots, for universal single-operation N-qubit quantum gate. A single two-level system controls the lineshapes, departing from optical-analog of electromagnetically-induced-transparency, with high fidelity and low photon loss.
By virtue of a silicon high-Q photonic crystal nanocavity, we propose and examine theoretically interactions between a stationary electron spin qubit of a semiconductor nanocrystal and a flying photon qubit.
