Optical Convolutional Neural Network with Atomic Non linearity — •Mingwei Yang1,2, Elizabeth Robertson2,3, Luisa Esguerra2,3, and Janik Wolters2,3 — 1Humboldt Universität zu Berlin, Newtonstr.15, D 12489 Berlin, Germany — 2Deutsches Zentrum für Luft und Raumfahrt e.V.

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.
