Optical neural networks: The 3D connection
Niyazi Ulaş Dinç, Demetri Psaltis, Daniel Brunner · Springer Link (Chiba Institute of Technology) · 2020
We motivate a canonical strategy for integrating photonic neural networks (NN) by leveraging 3D printing. Our belief is that a NN’s parallel and dense connectivity is not scalable without 3D integration. 3D additive fabrication complemented with photonic signal transduction can dramatically augment the current capabilities of 2D CMOS and integrated photonics. Here we review some of our recent advances made towards such an architecture.
