The quadrupole S1/2− D5/2 optical transition of a single trapped Ca+ ion and one of its vibrational sidebands are coupled to the standing wave field of a high finesse cavity. The coupling is verified by observing the ion’s response to both spatial and temporal variations of the intracavity field. Spatially, the standing wave is scanned with a visibility of 96.3 % which results in a spatial resolution of the intracavity field of 7 nm and 36 nm at points of largest and smallest slopes of the field, respectively. The deterministic control of the coupling of the ion’s electronic and vibrational states to the cavity field are a key step towards realization of the atom-photon interface in quantum computing and communication schemes with trapped ions.
