The total internal refection ellipsometry (TIRE) method was used for the generation and study of the hybrid TPP-SPP mode on a photonic crystal structure with a thin layer of silver and graphene/PMMA. Raman spectroscopy showed a consistent monolayer graphene present on the Ag layer. Recent studies have also shown that TPP and SPP components in the hybrid plasmonic mode is sensitive to the variation of coupling strength due to presence of the graphene monolayer. The decrease of the TPP and SPP dip components in the TPP-SPP hybrid mode can be explained by the changes of the conductivity of the silver layer due to the presence of this additional graphene/PMMA structure, which results in the non-optimal resonance conditions for the hybrid plasmonic mode. The modified positions of the TPP and SPP components in the wavelength spectra when compared to their original, separate excitations, indicates a strong coupling regime. The design of these hybrid plasmonic/graphene-based nanostructures has attractive capabilities for the development of advanced optical sensors and integrated optical circuit technologies.

石墨烯层对Tamm-等离激元混合极化模式中强耦合的影响

使用总内部椭偏椭圆仪（TIRE）方法在具有银和石墨烯/ PMMA薄层的光子晶体结构上生成和研究杂化TPP-SPP模式。拉曼光谱表明在Ag层上存在一致的单层石墨烯。最近的研究还表明，由于存在石墨烯单层，混合等离子体激元模式下的TPP和SPP组分对偶联强度的变化敏感。在TPP-SPP混合模式下，TPP和SPP浸渍组分的减少可以解释为，由于存在这种额外的石墨烯/ PMMA结构，银层的电导率发生了变化，这导致了非最佳共振条件用于混合等离子体模式。与原始的，单独的激发相比，TPP和SPP成分在波长谱中的修饰位置表明了强耦合机制。这些基于等离激元/石墨烯的纳米结构的设计对于先进的光学传感器和集成光学电路技术的开发具有吸引人的能力。
