  In this work, we discuss our vision for neuromorphic accelerators based on
integrated photonics within the framework of the Horizon Europe NEUROPULS
project. Augmented integrated photonic architectures that leverage phase-change
and III-V materials for optical computing will be presented. A CMOS-compatible
platform will be discussed that integrates these materials to fabricate
photonic neuromorphic architectures, along with a gem5-based simulation
platform to model accelerator operation once it is interfaced with a RISC-V
processor. This simulation platform enables accurate system-level accelerator
modeling and benchmarking in terms of key metrics such as speed, energy
consumption, and footprint.
