  Tremendous enhancement of light-matter interaction in plasmon-excited
molecular hybrid devices allows for non-linearities on the level of single
emitters and few photons. This promises a plethora of novel applications like
single photon transistors. Nevertheless, building the components of such
devices is technologically extremely challenging. We tackle this task by
lithographically fabricating on-chip plasmonic waveguides, efficiently
connected to far-field in- and out-coupling ports via low-loss dielectric
waveguides. Furthermore, a nano-assembling technology is developed, enabling
the controlled coupling of single organic emitters to the plasmonic waveguides.
Dibenzoterrylene fluorescent molecules hosted in anthracene crystals are
investigated for this purpose. Here we present all key-components and
technologies for a plasmon-excited single molecule non-linear device.
