Abstract

In this work, we present an optical spike processing architecture based on the combined operation of two types of photonic systems: silicon photonics (SiPh) microring resonator (MRR) weight banks [1] and all-optical spiking artificial neurons based on vertical cavity surface emitting lasers (VCSELs) [2]. These systems have been previously demonstrated as key-enabling building blocks in the rapidly growing field of neuromorphic photonics.
