Dr. Sina Saravi’s research group Metasurfaces for Diffractive Deep Neural Networks (MetaNN) has recently won 1,500,000 € in funding from the Carl-Zeiss-Stiftung (CZS) as part of the CZS Nexus program. Dr. Saravi has been a postdoctoral researcher specializing in nanooptics at the University of Jena since 2018, where he also earned his Ph.D. in physics after studying electrical engineering in Iran. In 2023, he was awarded the status of an ACP principal scientist.

Metasurfaces for Diffractive Deep Neural Networks (MetaNN)

Dr. Saravi’s research group MetaNN aims to investigate the fundamental and technological aspects of the use of nanostructured metasurfaces as a platform for optical diffractive neural networks to allow for their implementation. Neural networks of this type constitute an optical computer with sequential layers of linear and non-linear metasurfaces with specific parameters. This optical system will have an architecture similar to a deep neural network, but the design parameters will be obtained through machine learning on an everyday computer.

In the long term, these purely optical neural networks could be used as substitutes for certain computer-aided implementations of artificial neural networks to both increase processing power as well as to decrease electricity consumption; both improvements are important prerequisites for the continuing development of artificial intelligence systems.
