Total internal reflection ellipsometry was employed for the excitation and study of hybrid Tamm plasmon-surface plasmon polaritons mode. Simple optical methodology using optical filters to cut the part of incident light spectra was proposed. Using optical filters measured energy spectra was divided into two parts where in each range only one branch of the hybrid TPP-SPP plasmonic mode was excited directly by the incident light. Present experimental studies have shown, that if the investigated system is in strong coupling, this is always enough to excite only one component of the hybrid excitation. Thus, its dispersion relation will be the same as when the excitation is done with a whole spectrum. In the case of the TPP-SPP hybrid mode where strong coupling is realized only in p-polarized light, the fitting results have shown that the strongest coupling was at the point where the noninteracting TPP and SPP curves should be crossing. The obtained Rabi splitting for the hybrid TPP and SPP modes in BK7 prism/1D PC TiO 2 /SiO 2 (60 nm/110 nm)/TiO 2 (30 nm)/Au (40 nm) multilayered structure was about 105 meV.

Tamm等离子体-表面等离子体激元混合模式中强耦合机制的实验证据

采用全内反射椭圆偏振法激发和研究了混合Tamm等离激元-表面等离激元极化子模式。提出了一种简单的光学方法，即使用滤光器来切割入射光谱的一部分。使用光学滤光片，将测得的能谱分为两部分，其中在每个范围内，混合TPP-SPP等离子体模式仅一个分支被入射光直接激发。当前的实验研究表明，如果所研究的系统处于强耦合状态，则总是足以激发混合激励的一个分量。因此，其色散关系将与使用整个光谱进行激发时的色散关系相同。对于仅在p偏振光中实现强耦合的TPP-SPP混合模式，拟合结果表明，最强的耦合位于非相互作用的TPP和SPP曲线应相交的点。在BK7棱镜/ 1D PC TiO 2 / SiO 2（60 nm / 110 nm）/ TiO 2（30 nm）/ Au（40 nm）多层结构中，TPP和SPP混合模式的Rabi分裂约为105 meV。
