Electrical control of the nonlinear properties of plasmonic nanostructures

Abstract : This work brings nano-electronics and nano-photonics technologies together to create an electron- plasmon device whose linear and nonlinear optical properties are electrically controlled. Here, we present the first demonstration of nonlinear photoluminescence modulation by electrical means in an uncluttered configuration. To this purpose, plasmonic nanoantennas are interfaced with elec- trical connections inducing localized regions of electron accumulation and depletion and therefore affecting the optical response. Additionally, a complete analysis of the nonlinear photoluminescence in plasmonic nanowires is carried out. The delocalization and transport of nonlinearities provided by such structures allow the remote activation of the signals. Different aspects including the un- derlying mechanisms behind the electrical modulation and the processes dictating the nonlinear photoluminescence generation are systematically explored.
