VCSELs for fast neuromorphic photonic systems operating at GHz rates
Matéj Hejda, Joshua Robertson, Julián Bueno, Antonio Hurtado · 2020
We report experimentally on VCSEL-based artificial optical spiking neurons with ultrafast spiking refractory period; hence allowing operation at GHz rates. This feature is used to demonstrate all-optical digital-to-spiking information format conversion at 1.0 Gbps.
