Abstract
We present experimental results showing phonon-mediated coupling between two quantum dots embedded inside a photonic-crystal microcavity. With only one of the dots being spectrally close to the cavity, we observe both frequency up-conversion and down-conversion of the pump light via a 1.2-THz phonon. We demonstrate this process for both weak and strong regimes of dot-cavity coupling and provide a simple theoretical model to qualitatively explain our observations.
