We are conducting research on the spectroscopic properties of exciton-optical cavity strong coupling systems. In our previous studies, we have elucidated the near-field excitation spectroscopic characteristics and dephasing dynamics in the strong coupling system between J-aggregates of tetraphenylporphyrin derivatives and plasmons. In this study, we investigated the spectral properties and ultrafast dynamics of the strong coupling systems between exciton and optical cavity modes, which facilitates the suppression of electron transfer to gold and provides easy access to excitation spectrum measurements.
