Abstract

Photonic data routing in optical networks overcomes the limitations of electronic routers with respect to data rate, latency, and energy consumption while suffering from dynamic power consumption, non-simultaneous usage of multiple wavelength channels, and large footprints. Here we show the first hybrid photonic-plasmonic, non-blocking, broadband 5x5 router. The compact footprint (<250 {\mu}m2) enables high operation speed (480 GHz) requiring only 82 fJ/bit (1.9 dB) of averaged energy consumption (routing loss). The router supports multi-wavelength up to 206 nm in the telecom band. Having a data-capacity of >70 Tbps, thus demonstrating key features required by future high data-throughput optical networks.
