In this work, light−matter interaction is explored in a hybrid device, consisting of a microfiber cavity and a plasmonic nanoparticle. Perovskite nanowires are embedded in the microcavity and cylindrical nanoholes are formed on the surface of the structure to facilitate generating a hybrid photonic-plasmonic resonator. A spherical gold nanoparticle with a diameter of 15 nm, coated with a 15 nm polymer layer, is placed inside one of the cylindrical nanoholes on the surface of the microdevice to interact the localized surface plasmons with the cavity’s mode field. The device enables extreme light localization through concurrently coupling the emitter’s light into the optical mode field and strong plasmonic field, causing a significant change in the localized density of the electromagnetic states. Time resolved experiments, based on a single photon counting technique, are performed and single-atom cooperativity parameters procedure is applied to determine the enhancement of the light−matter interaction in the presence of the plasmonic nanoparticle. Consequently, light−matter interaction enhances by a factor of 6.4 upon coupling of the Perovskite nanowire into the hybrid photonic-plasmonic mode.
