The nitrogen-vacancy (NV) centre is a promising single photon source in the solid state. Control over NV centre emission properties as well as surface plasmon propagation is important for many quantum applications including quantum repeaters and single photon transistors. This implies efficient coupling of the NV centre to guided modes of the electrical field. One possible approach is to concentrate optical fields at the NV centre location. These strong fields can be obtained by metallic antenna structures. We investigate field enhancement and increased decay rate of the NV centre, both being indications of strong electrical fields, for different metallic antenna structures.
