Abstract
We demonstrate several building blocks for an ion-photon interface based on a
trapped Ca ion in an optical cavity. We identify a favorable experimental
configuration and measure system parameters, including relative motion of the
trapped ion and the resonator mode. A complete spectrum of cavity-assisted
Raman transitions between the $4^2S_1/2$ and $3^2D_5/2$ manifolds is
obtained. On two of these transitions, we generate orthogonally polarized
cavity photons, and we demonstrate coherent manipulation of the corresponding
pair of atomic states. Possible implementations of atom-photon entanglement and
state mapping within the ion-cavity system are discussed.
