Light twists around plasmonic nanowires (Conference Presentation)
Author(s): Laurens Kuipers

Paper Abstract

We use a near-field microscope to visualize the nanoscale light patterns, both electric and magnetic fields [1,2]. The interplay between the various components of either the magnetic or the electric fields leads to optical entities that, in their size, put nanophotonics to shame: these optical singularities have a size zero. Interestingly, optical singularities near nanoscale structures exhibit a markedly different behavior from those in macroscopic beams [3,4]. We observe a distinctly different behavior around plasmonic nanowires to that above photonic crystal waveguides [5]. Moreover, we show that these singularities and their associated local helicity can be applied for new quantum technology as they can be used to deterministically couple a spin-transition to emission direction [6], useful for novel quantum technology [7]. In addition we show that plasmonic nanowires are better than dielectric waveguides for the transmission of ultrashort pulses [8]. This can also be used to induce nonlinear phenomena [9].
