Spin-polarized photon emission by resonant multipolar nanoantennas

Kruk, Sergey; Decker, Manuel; Staude, Isabelle; Schlecht, Stefan; Greppmair, Michael; Kivshar, Yuri; Neshev, Dragomir


We demonstrate nanoscale spin control of photons emitted by an atomic system coupled to a compact plasmonic nanoantenna supporting phase-locked interference of different multipolar moments within a single resonance. Experimentally we observe chiral light emission from quantum dots over split-ring resonant nanoantennas, where the spin of the emitted photons is locked to their transverse momentum. We demonstrate that the polarization can vary from linear to elliptical with ellipticity reaching...[Show more]
