The radiative coupling between quantum emitters and surface plasmon polaritons (SPPs) plays a key rule in designing hybrid plasmonic devices with active functionalities such as ultrafast all-optical switching, lasing as well as energy transfer and storage. We investigate the strong coupling between surface plasmon polaritons and excitons in metal-molecular aggregate hybrid nanostructures by linear spectroscopy combined with spectral interferometry. The spectral amplitude and phase information are used to reconstruct the response function of the hybrid system which provides an effective way to monitor the polarization response on the field level and gives a complete picture and accurate evaluation of the optical property of the strongly radiatively coupled exciton-SPP system. Model calculations confirm our experimental results and reveal novel features of these interactions such as the formation of sub- and superradiant states. Our field-level investigation of such coupled hybrid systems is expected to be of importance for understanding and manipulating the light-molecule interaction as well as for future implementations of active plasmonic devices.
