ABSTRACT The field of plasmonics1 offers a route to control light fields with metallic nanostructures through the excitation of surface plasmon polaritons2. These surface waves, bound to a

metal dielectric interface, can tightly confine electromagnetic energy3. Active control over surface plasmon polaritons has potential for applications in sensing4, photovoltaics5, quantum

communication6,7, nanocircuitry8,9, metamaterials10,11 and super-resolution microscopy12. We achieve here active control of plasmonic fields using a digital spatial light modulator.

Optimizing the plasmonic phases through feedback, we focus surface plasmon polaritons at a freely prechosen point on the surface of a nanohole array. Digital addressing and scanning of
