We investigate the enhancement of the resonance energy transfer rate between donor and acceptor associated by the surface plasmons of the Ag nanorods on a SiO2 substrate. Our results for a single nanorod with different cross sections reveal that the cylinder nanorod has the strongest ability to enhance the resonance energy transfer rate. Moreover, for donor and acceptor with nonparallel polarization directions, we propose simple V-shaped nanorod structures which lead to the remarkable resonance energy transfer enhancement that is ten times larger than that by the single nanorod structure. We demonstrate that these structures have good robustness and controllability. Our work provides a way to improve the resonance energy transfer efficiency in integrated photonic devices.

我们研究了在 SiO2 衬底上的 Ag 纳米棒的表面等离激元作用下，供体和受体之间的共振能量转移速率的增强。我们对不同横截面的单个纳米棒的研究结果表明，圆柱形纳米棒具有最强的增强共振能量转移速率的能力。此外，对于具有非平行偏振方向的供体和受体，我们提出了简单的 V 形纳米棒结构，这导致了显著的共振能量转移增强，比单个纳米棒结构的增强大十倍。我们证明了这些结构具有良好的鲁棒性和可控性。我们的工作为提高集成光子器件中的共振能量转移效率提供了一种方法。PACS：78.67.Qa，73.20.Mf，42.50.Ex。
