Optically resonant crossbar metasurface architectures

Crossbar architectures are a highly popular platform in the electronics industry for enabling high-component density at the nanoscale, in today’s constantly shrinking electronic devices. These structures are akin to metal-insulator-metal (MIM) architectures widely used in nanophotonics and are key to the realization of a range of reconfigurable and addressable metasurfaces. Therefore, the application of nanophotonic design principles to such electronic platforms provides an unexplored path towards the integration of nanophotonic technologies into telecommunication and computing platforms. We show here that these crossbar-architectures can be engineered to act as addressable metasurfaces exhibiting, multispectral optical resonances forming the basis for next-generation optical computing systems, while still preserving their electronic functionality.
