Abstract

Pairs of interconnected brain-inspired photonic synapses (connected in-parallel and in-series) are developed using Vertical Cavity Surface Emitting Lasers (VCSELs). We discuss the operation of each configuration and demonstrate their capability to perform different spike-based processing tasks including information encoding, temporal filtering, and Multiply-and-Accumulate (MAC) operations.
