Strong coupling (SC) of light and matter states at ambient conditions is of interest in quantum technologies. In previous work, we demonstrated ambient condition SC between single quantum dots and a plasmonic slit resonator at a scanning probe tip [1,2]. To gain stability and scalability we have now developed an on-chip platform. We fabricate plasmonic slit resonators on a glass substrate located at the tip of a first electrode structure opposed by a second electrode. We then use dielectrophoresis to attract & position single quantum dots at the nanoresonator. This combination of techniques provides additional degrees of freedom as well as the opportunity to apply electric fields to tune the system.
