Typically used plasmonic wires introduce prohibitive losses, perform poorly for long-reach interconnects because of low-directive radiation and low efficiency. Researchers in Spain have designed a class of slot-waveguide-based silicon nanoantennas that address these limitations. To test the performance of these antennae, an on-chip plasmonic-dielectric interconnect was experimentally demonstrated over distances as high as 100 μm. The wireless scheme clearly outperformed previous plasmonic approaches in terms of link efficiency and effective gain. This work paves the way for the development of ultrafast on-chip wireless reconfigurable and flexible interconnects and opens new avenues in optical manipulation and sensing applications…read more.
