Measurements of the femtosecond relaxation dynamics of Tamm plasmon-polaritons

This paper reports on measurements of the lifetime of Tamm plasmon-polaritons (TPPs) excited in a 1D photonic-crystal/thin-metal-film structure. A femtosecond pulse reflected from a structure of this kind is found to be significantly distorted if its spectrum overlaps with the Tamm plasmon resonance...

Description
Summary:This paper reports on measurements of the lifetime of Tamm plasmon-polaritons (TPPs) excited in a 1D photonic-crystal/thin-metal-film structure. A femtosecond pulse reflected from a structure of this kind is found to be significantly distorted if its spectrum overlaps with the Tamm plasmon resonance. It is shown that the TPP lifetime possesses strong polarization and angular dependence. It varies from 20 fs for p-polarized light to 40 fs for s-polarized light at a 45° angle of incidence. The reported lifetime of Tamm plasmons is several times smaller than the previously reported lifetime of surface plasmons.
