Optical Convolutional Neural Network with Atomic Non linearity — •Mingwei Yang^1,2, Elizabeth Robertson^2,3, Luisa Esguerra^2,3, and Janik Wolters^2,3 — ¹Humboldt Universität zu Berlin, Newtonstr.15, D 12489 Berlin, Germany — ²Deutsches Zentrum für Luft und Raumfahrt e.V. (DLR), Rutherfordstraße 2, D 12489, Berlin, Germany — ³Technische Universität Berlin, Straße des 17. Juni 135, D 10623, Berlin, Germany

An optical convolutional neural network is demonstrated in which linear operations are implemented by lenses and spatial light modulators (SLMs), while an optical nonlinearity is realized by a cesium vapor cell as a saturable absorber. We use this network to demonstrate non-linear image processing, as well as to improve the classification of the MNIST data by a single layer fully connected.
