Abstract:
We use chirp-compensated spectral interferometry to fully probe the optical response of strongly coupled excitons (Xs) and surface plasmon polaritons (SPPs) in J-aggregate/metal hybrid nanostructures at a field level. The effect of higher order chirp in the interferometric arms on the spectral phase retrieval is theoretically and experimentally analyzed. A quantitative description of the X-SPP polariton response is precisely obtained by simultaneously fitting the measured spectra and phases to a Fano lineshape model. We further deduced the time structure of the reemitted polariton field by Fourier transform to the time domain, which shows clear damped polarization oscillations within an ultrashort time scale of 100 fs.
