Ultrafast Emulation of Retinal Neuronal Circuits with Artificial VCSEL Optical Neurons

Abstract

Biological retinal neuronal circuits are emulated using a system of connected 1550 nm Vertical-Cavity Surface-Emitting Laser (VCSEL)-neurons. Spiking and non-spiking neuronal responses are reproduced at ultrafast speed (>7 orders of magnitude faster than neurons) with prospects for novel braininspired computing platforms and Artificial Intelligence.
