spelling Tuning Spontaneous Emission through Waveguide Cavity Effects in Semiconductor NanowiresDirnberger, F.Abujetas, Diego R.König, J.Forsch, M.Koller, Thomas M.Gronwald, I.Lange, C.Huber, R.Schüller, C.Korn, T.Sánchez-Gil, José A.Bougeard, D.Semiconductor nanowireLuminescence lifetimeTunable spontaneous emissionPhotonic waveguide cavityFree excitonsSubwavelength nanophotonics6 pags., 4 figs.The ability to tailor waveguide cavities and couple them with quantum emitters has developed a realm of nanophotonics encompassing, for example, highly efficient single photon generation or the control of giant photon nonlinearities. Opening new grounds by pushing the interaction of the waveguide cavity and integrated emitters further into the deep subwavelength regime, however, has been complicated by nonradiative losses due to the increasing importance of surface defects when decreasing cavity dimensions. Here, we show efficient suppression of nonradiative recombination for thin waveguide cavities using core-shell semiconductor nanowires. We experimentally reveal the advantages of such nanowires, which host mobile emitters, that is, free excitons, in a one-dimensional (1D) waveguide, highlighting the resulting potential for tunable, active, nanophotonic devices. In our experiment, controlling the nanowire waveguide diameter tunes the luminescence lifetime of excitons in the nanowires across 2 orders of magnitude up to 80 ns. At the smallest wire diameters, we show that this luminescence lifetime can be manipulated by engineering the dielectric environment of the nanowires. Exploiting this unique handle on the spontaneous emission of mobile emitters, we demonstrate an all-dielectric spatial control of the mobile emitters along the axis of the 1D nanowire waveguide.We gratefully acknowledge financial support by the German Research Foundation (DFG) via SFB 689 and 1277 Project A01.
