Coupling organic molecules to integrated optical circuits is a promising route to creating compact and controlled ensembles of interacting quantum emitters. We present our recent advances in realizing such an experimental platform based on sub-wavelength waveguides (nanoguides) and micro-resonators on a chip. We demonstrate the coupling of single molecules to linear nanoguides [1,2] and the control of the resonance frequencies via integrated microelectrodes [2,3]. Since the coupling efficiency between the molecule and the nanoguide is inherently limited by geometric and material constraints, we employed different host matrices and discuss various resonator designs to enhance the coupling. We demonstrate a resonator finesse up to 250 (Q=16000), leading to significant Purcell enhancement and extinction dips of 60 % [3]. Furthermore, we show the controlled manipulation and tuning of molecular resonances, leading to the simultaneous coupling of two individual molecules to well-defined resonator modes [3].
