Wavefront Shaping of Plasmonic Beams by Selective Coupling
Custom
plasmonic beams are advantageous for numerous scientific
and technological aspects. While plasmonic wavefront shaping had traditionally
been a truly planar process, taking place on a single surface, here
we explore a new method for plasmonic shaping by selectively coupling
plasmonic waves between different surfaces of an insulator–metal–insulator
structure. In contrast to most previous shaping techniques that rely
on free-space illumination, here the plasmonic beam in the buried
surface acts as the light source. We demonstrate, both experimentally
and numerically, a way to tailor the amplitude and phase of the wavefront
using this new technique. The proposed method can be used to efficiently
shape the plasmonic beam, for potential applications in sensing, interferometry,
and communications
