One-dimensional subwavelength waveguides (nanoguides) promise efficient light-matter interactions between photons in the waveguide mode and individual emitters separated on length scales much longer than their transition wavelength [1,2]. We report on the coupling of organic dye molecules at low temperatures to the confined mode of a TiO2-waveguide via the evanescent field and demonstrate external control on the resonance frequencies of the molecules via the DC Stark effect. This allows one to match the resonance frequencies of two emitters, thus controlling their coherent coupling via the nanoguide. In future, we want to boost our emitter-nanoguide coupling by the use of on-chip resonators [3]. This will enable us to build up a network of strongly coupled quantum emitters and study the emergence of polaritonic states [4].
