How to Obtain the Correct Rabi Splitting in a Subwavelength Interacting System
We unambiguously extract the individual decay channels
of a coupled
plasmon-exciton system by using correlated single-particle absorption
and scattering measurements. A remarkable difference in the two channels
is presentclear Rabi splitting in the plasmon channel but
no Rabi splitting in the exciton channel. Discordance in the absorption
and scattering spectra are mainly originated from the distinct contributions
of plasmon and exciton channels in the absorption and scattering process.
Our findings provide insights into plasmon-exciton interaction in
an open cavity and can impact the design of plexcitonic devices for
ultrafast nonlinear nanophotonics
