nanoantennas are of key relevance for advanced functionalities
to be implemented at the nanoscale and, in particular, for color routing
in an ultracompact flat-optics configuration. Here we demonstrate
a novel approach avoiding complex collective geometries and/or restrictive
morphological parameters based on cross-polarized detuned plasmonic
nanoantennas in a uniaxial (quasi-1D) bimetallic configuration. The
nanofabrication of such a flat-optics system is controlled over a
large area (cm2) by a novel self-organized technique exploiting
ion-induced nanoscale wrinkling instability on glass templates to
engineer tilted bimetallic nanostrip dimers. These nanoantennas feature
broadband color routing with superior light scattering directivity
figures, which are well described by numerical simulations and turn
out to be competitive with the response of lithographic nanoantennas.
These results demonstrate that our large-area self-organized metasurfaces
can be implemented in real-world applications of flat-optics color
routing from telecom photonics to optical nanosensing.
