Optical spiking neuronsResearch Area:
Neuromorphic computing enabled by integrated photonics Main Researcher: Thomas Van Vaerenbergh
Our brains typically process information that is encoded in spike trains. This is a hybrid analog/digital processing scheme that has important advantages in terms of robustness and flexibility.
An important ingredient here is the concept of excitability: provided the input is large enough, the system sends out a pulse with a fixed shape.
We are investigating how to translate these concepts to photonic devices and how to cascade these photonic neurons.
