One-dimensional subwavelength waveguides (nanoguides) are very promising candidates for exploring the rich physics of quantum many body systems, since they allow one to couple several emitters, e.g. organic dye molecules, to a single one-dimensional light mode. However, the efficiency of coupling between an individual emitter and a realistic nanoguide is limited by geometric/material constrains and a rich internal level structure of the emitters. To address this issue, one can employ a high-finesse Fabry-Pérot cavity [1] to enhance the emission of molecules into the mode of interest. Here, we report on seven-times enhancement of the coupling by using microring resonators [2]. We report on our progress to improve our experimental platform by advances in the fabrication and the use of higher refractive index materials such as GaP. Together with the ability to manipulate the resonance frequencies of the molecules by static electric fields, we plan to investigate cooperative effects among several emitters [3].
