We study the influence of coherent inter-dot coupling on the transport properties of quantum dot arrays. The magneto-conductance oscillations observed in these open devices show a marked reduction in amplitude, and an associated suppression of their high frequency content, as we reduce the strength of the inter-dot coupling. We discuss these observations in the context of a transition from molecular-to atomic-like interference, which is induced as we suppress the strength of the inter-dot coupling.
