Spin and angular momenta of light are important degrees of freedom innanophotonics which control light propagation, optical forces and informationencoding. Typically, optical angular momentum is generated using q-plates orspatial light modulators. Here, we show that graphene-supported plasmonicnanostructures with broken rotational symmetry provide a surprising spin toorbital angular momentum conversion, which can be continuously controlled bychanging the electrochemical potential of graphene. Upon resonant illuminationby a circularly polarized plane wave, a polygonal array of indium-tin-oxidenanoparticles on a graphene sheet generates scattered field carryingelectrically-tunable orbital angular momentum. This unique photonic spin-orbitcoupling occurs due to the strong coupling of graphene plasmon polaritons andlocalised surface plasmons of the nanoparticles and leads to the controlleddirectional excitation of graphene plasmons. The tuneable spin-orbit conversionpave the way to high-rate information encoding in optical communications,electric steering functionalities in optical tweezers, and nanorouting ofhigher-dimensional entangled photon states.
