Precise positioning of single quantum dots (QDs) in photonics crystal (PhC) cavities with nanometer-scale accuracy offers great promise for on-chip integrated quantum photonic circuit. In such coupled QD-cavity system, the decoherence fundamentally affects the coherent control for quantum communication and information processing. However, accessing to the strong-coupling regime and the impact of pure dephasing in such system have been rarely reported yet. Here, relying on our unique site-controlled pyramidal InGaAs/GaAs QDs – high-Q-PhC cavities platform, we investigate the cavity quantum electrodynamics towards strong-coupling regime mediated by pure dephasing. We demonstrate the anti-crossing and mutual linewidth narrowing of the single excitonic emission strongly coupled to cavity mode near resonance. We further present the signatures of Rabi-like oscillation and quantum beating between upper and lower branch of polariton.
