我们提出了一种方案,用于两个远距离光发射器之间的有效的长距离能量转移,所述远距离光发射器被多于一个波长的光分离,即远远超出经典的福斯特半径。混合纳米天线-波导系统介导能量的传输,与真空相比显示出高达10(8)的增强。我们的模型显示了如何在纳米结构的介质中的能量转移可以提高,超越简单的供体珀塞尔增强,特别是对于大的供体-受体分离。我们提出的方案连接现实的发射器,并可能导致实际的片上实现。
We propose a scheme for efficient long-range energy transfer between two distant light emitters separated by more than one wavelength of light, i.e. much beyond the classical Forster radius. Ahybrid nanoantenna-waveguide system mediates the transmission of energy, showing enhancements up to 10(8) as compared to vacuum. Our model shows how energy transfer in nanostructured media can be boosted, beyond the simple donor Purcell enhancement, and in particular for large donor-acceptor separations. The scheme we propose connects realistic emitters and could lead to practical on-chip implementations.
