Multi-channel Optical Vision Model
Ali Momeni, Guillaume Noetinger, Tim Tuuva +1
Spatial multiplexing is one of the natural strengths of optics, yet in optical neural networks, it is often used mainly as parallel throughput. Here, we show that spatial multiplex…

Dynamical frustration in spacetime metamaterials enables cascading logic and synchronization
Rupesh Mahore, Oleksandr Gamayun, Guillaume Noetinger +3
Spacetime metamaterials are engineered media whose constitutive parameters such as permittivity, permeability, stiffness, or mass density are modulated simultaneously in both space…

Tutorial: A practical guide to the alignment of defocused spatial light modulators for fast diffractive neural networks
Guillaume Noetinger, Tim Tuuva, Romain Fleury
The conjugation of multiple spatial light modulators (SLMs) enables the construction of optical diffractive neural networks (DNNs). To accelerate training, which is limited by the…
