Raman amplification enhanced by surface plasmon resonances

我们提出利用长程表面等离子激元模式来降低等离子体晶体中表面等离子激元在传播过程中的吸收损耗，等离子体晶体是周期性波纹的金属表面，具有不对称的层状结构。我们从实验上证实了这一效应。利用严格耦合波分析技术，从理论上分析了等离子体晶体的色散关系和辐射特性，并将其应用于有机电致发光二极管发光效率的提高。我们还分析了等离子体晶体表面附近荧光分子的能量耗散。

We proposed the use of long-range surface plasmon modes to reduce the absorption loss in the propagation of surface plasmons in plasmonic crystals, which is periodically corrugated metal surfaces, with an asymmetric layer structure. We confirmed this effect experimentally. We theoretically analyzed the dispersion relations and the radiation properties of plasmonic crystals using the rigorous coupled wave analysis technique and adopted the results to the enhancement of emission efficiency of organic light-emitting diodes. We also analyzed energy dissipation of fluorescent molecules in the proximity of the surface of plasmonic crystals.
