Abstract

We investigate theoretically the possibility of the excitation of a confined state of the electromagnetic field at the metal-less structures, which can be referred to as optical Tamm plasmons. In contrast to the ordinary surface plasmons, Tamm plasmons can be formed with either s- or p- polarization and its dispersion lies within the light cone, and thus it can be optically excited without the structure of prisms or gratings. In this study, we calculate the reflectance and electromagnetic field distributions of both s and p waves incident on metal-less systems in a numerically exact manner, using the invariant imbedding method of wave propagation in linear and nonlinear stratified media. We have observed the dip of the reflectance for the both s and p wave cases. We show that the electromagnetic field enhancement and the influence of nonlinearity due to the excitation of Tamm plasmons are much stronger than those due to conventional surface plasmons.
