Full Name: Photonic Network-on-Wafer for Multi-Tile GPUs: From Architecture to Hardware Implementation

Duration: 1/1/2021-31/12/2025

Objective:

A new compute paradigm is proposed, based on large arrays of graphics processing units (GPUs) that are interconnected via a wafer-scale photonic network. This results in unprecedented performance at low power. A holistic study of this new paradigm will be carried out, ranging from the design of a suitable computer and network architecture to the implementation of key hardware components.

INTEC's Role:

Development of the photonic network-on-wafer including optical switching functionality and transfer printed GaAs QD lasers/amplifiers and Si photonic optical transceivers
