Observation of enhanced spontaneous and stimulated emission of GaAs/AlGaAs nanowire via the Purcell effect
Source abstract
Abstract
We experimentally demonstrated enhanced spontaneous and stimulated emission of GaAs/AlGaAs nanowire via the Purcell effect. By integrating the NW and SiO2-Au substrate, the hybridization of the dielectric modes in the NW with surface plasmons on the surface of Au formed hybrid plasmonic modes. Taking advantage of the nanolocalized electromagnetic field of hybrid plasmonic modes, the intensities of spontaneous and stimulated emission were enhanced via the Purcell effect by factors of four and ten, respectively. More importantly, the plasmonic lasing action was continuous-wave under the continuous-wave pump.
