摘要

Abstract

The electromagnetic field scattered by nano-objects contains a broad range of wavevectors and can be efficiently coupled to waveguided modes. The dominant contribution to scattering from subwavelength dielectric and plasmonic nanoparticles is determined by electric and magnetic dipolar responses. Here

we experimentally demonstrate spectral and phase selective excitation of Janus dipoles

sources with electric and magnetic dipoles oscillating out of phase

in order to control near-field interference and directional coupling to waveguides. We show that by controlling the polarisation state of the dipolar excitations and the excitation wavelength to adjust their relative contributions

directionality and coupling strength can be fully tuned. Furthermore

we introduce a novel spinning Janus dipole featuring cylindrical symmetry in the near and far field

which results in either omnidirectional coupling or noncoupling. Controlling the propagation of guided light waves via fast and robust near-field interference between polarisation components of a source is required in many applications in nanophotonics and quantum optics.
