耦合表面等离子体极化激元 (SPP) 可以有效地将激发能量从供体分子转移到厚度达 120 纳米的金属膜相对两侧的受体分子。这种辐射转移的变体应该允许通过使用适当设计的金属纳米结构来定向控制激发能量的流动，并通过SPP介导10(-7)至10(-4)米长度范围内的转移。在新兴的纳米光子学领域，这种前景可能允许对光进行亚波长尺度的操纵，并提供与外界的接口。
Coupled surface plasmon polaritons (SPPs) are shown to provide effective transfer of excitation energy from donor molecules to acceptor molecules on opposite sides of metal films up to 120 nanometers thick. This variant of radiative transfer should allow directional control over the flow of excitation energy with the use of suitably designed metallic nanostructures, with SPPs mediating transfer over length scales of 10(-7) to 10(-4) meters. In the emerging field of nanophotonics, such a prospect could allow subwavelength-scale manipulation of light and provide an interface to the outside world.
