Active spatial control of plasmonic fields
| Abstract | The field of plasmonics offers a route to control light fields withmetallic nanostructures through the excitation of Surface PlasmonPolaritons (SPPs). These surface waves, bound to a metal dielectricinterface, tightly confine electromagnetic energy. Active control overSPPs has potential for applications in sensing, photovoltaics, quantumcommunication, nano circuitry, metamaterials and super-resolutionmicroscopy. We achieve here a new level of control of plasmonic fieldsusing a digital spatial light modulator. Optimizing the plasmonic phasesvia feedback we focus SPPs at a freely pre-chosen point on the surfaceof a nanohole array with high resolution. Digital addressing andscanning of SPPs without mechanical motion will enable novelinterdisciplinary applications of advanced plasmonic devices in cellmicroscopy, optical data storage and sensing. |
