Abstract
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 Förster radius. A hybrid nanoantenna-waveguide system mediates the transmission of energy, showing enhancements up to 108 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.
Highlights
Energy transfer between an excited two level quantum emitter and an equivalent one in its ground state is a key process in many physical systems
We have presented enhanced long-range energy transfer mediated by a complex hybrid photonic environment where donor and acceptor are coupled to metallic antennas linked by a dielectric waveguide
We report 2 × 10−6 absolute energy transfer to donor decay rate, which suggests that experimental verification could be done for donor–acceptor distances of several wavelengths

Our model shows how energy transfer in nanostructured media can be the work, journal citation boosted, beyond the simple donor Purcell enhancement, and in particular for large donor–acceptor and DOI.
