When light interacts with metal surfaces it excites electrons which can form propagating excitation waves called surface plasmon polaritons (SPP). These collective electronic excitations allow for many applications due to their ability to produce electric fields, localized to sub-wavelength scales. It was shown that the emission of single quantum systems like e.g. quantum dots [1] or nitrogen vacancy centres in diamond [2] can be used to generate propagating single surface plasmon polaritons. In the frame of large scale quantum networks, further conceived experiments incooperate the incoupling of single narrowband emitters to plasmons. Such single emitters could be organic dye molecules serving as an element of e.g. a quantum phase gate. Here we present first experimental results on the coupling of single organic molecules to silver nanowires at cryogenic temperatures.
