Due to its fundamental significance as well as its applicability to, e.g., quantum networks, a wide variety of investigations exists dealing with the efficient coupling of photons and matter. Whether it is atoms in a cavity, in or close to a fiber or a waveguide, all these methods employ some sort of coupling tool to match the profile of the electromagnetic field to the atomic transition. The aim of our research is to couple the light field to an atomic ion directly, i.e. in free space. This requires excitation from the full solid angle for optimal field-transition overlap.
Our solution to this problem is to trap an ion with a single tip ion trap with wide optical access, which is placed inside the focus of a deep parabolic mirror. We examine experimental issues like loading and cooling in such a geometry, micro-motion compensation, optimization of the focal position and detection schemes.
