On-chip optical communication between individual nano optoelectronic components is important to reduce the footprint and improve energy efficiency of photonic neuromorphic solutions. Although nanoscale photon emitters receivers have been reported separately, them remains largely unexplored. We demonstrate direct on-chip directional broadcasting light InP nanowire photodiodes on silicon. The performance multiple wire-to-wire circuits mapped, demonstrating robust with up 5 bit resolution as needed in biological networks a minimum component driving power for continuous operation 0.5 μW which below that conventional hardware. results agree well theoretical modeling allows us understand network limits identify where significant improvements could be achieved. estimate an per ∼1 fJ signal fan-out from one emitter hundreds other nodes possible. find circuit parameters can satisfy quantitative requirements run tasks neural bioderived autonomous navigation.
