Debut! Smart Photonics group's first paper on Arxiv just two years after establishment
We are thrilled to announce that the Smart Photonics research group at Leibniz Institute for Photonic Technologies (Leibniz-IPHT) has achieved a significant milestone with the release of our first group-owned paper on Arxiv, only two years after the group's establishment in August 2022. The paper, titled "Nonlinear Inference Capacity of Fiber-Optical Extreme Learning Machines", investigates how nonlinear optical phenomena can serve as a fundamentally new resource for analog brain-inspired computing. Our team has demonstrated that nonlinear inference capacity scales with nonlinearity to the point where it surpasses the performance of a deep neural network model with five hidden layers on a scalable nonlinear classification benchmark. By comparing normal and anomalous dispersion fibers under various operating conditions against digital classifiers, we've established a direct correlation between the system's nonlinear dynamics and its classification performance.
We extend our sincere gratitude to the Carl Zeiss Foundation for their generous support through the CZS Nexus funding program, which has enabled the establishment and ongoing work of our research group. We also thank the Leibniz Institute for Photonic Technologies (Leibniz-IPHT) for providing the excellent research environment and resources necessary for our success.The paper is now available on Arxiv (arXiv:2501.18894 [physics.optics]) and is currently under review for a special issue. This milestone marks just the beginning of our journey to develop the next generation of smart photonic processors for modern diagnostics.

Welcome, Mehmet, to our Smart Team.
We are delighted to welcome Mehmet Müftüfglu, the newest member of our Smart Photonics Team, who joined us in January 2025. Mehmet has already pursued exceptional research studies during his Master's in our group, efforts which the Friedrich-Schiller-University Jena has acknowledged with an Honours fellowship and an excellent grading on his Master's thesis. He comes with a broad expertise in physics, photonics, machine learning and neuromorphic computing, the foundations of which he has built already through his Bachelor's at the Middle East Technical University (METU), Ankara, Turkey,, where she specialized in machine learning and optical systems. As part of her PhD research, he will focus on new neuromorphic wave computing frameworks in optical fibers, contributing to our group's core expertise.We warmly welcome him to our group and look forward to exciting learnings and fun experiments at the interface of light and information science.

Saturday lecture out now!
We are pleased to announce that the Saturday Physics lecture by Prof. Dr. Mario Chemnitz on "Von Neuronen zu Photonen: Wie Licht die künstliche Intelligenz revolutioniert" (held in German) from November 30, 2024, is now available online.In this entertaining presentation, Prof. Chemnitz illustrates how optical computing could transform AI technology. He discussed how optical neurons, based on principles such as diffraction, refraction, and interference, could offer more energy-efficient and faster alternatives to conventional electronic systems. On three experiments, the lecture introduces neural-like computing using lenses, fibers, and photonic chips, while examining both the development potential and current challenges in establishing optical neural networks as a future technology.Image courtesy: Simon Stützer (JANOVA).

Coffee Computer Captivates Crowds at Long Night of Science
At this year's Long Night of Science, over 850 visitors experienced an extraordinary fusion of everyday physics and cutting-edge computing at this year's Long Night of Science. One highlight was our unique Coffee Computer demonstration, in which a simple cup of coffee is transformed into an interactive computing device.Visitors watched in amazement as spoken words were converted into wave patterns on the coffee's surface through carefully placed speakers. These mesmerizing ripples demonstrated the principles of reservoir computing and neural networks in a uniquely accessible way. This allowed us to show how general wave mixing principles extend from coffee cups to optical fibers in modern computing applications.Our team was particularly thrilled by the enthusiastic engagement from visitors of all ages, who brought boundless curiosity and excitement to each demonstration. Thank you to everyone who joined us for this illuminating evening of discovery.

Dr. Mario Chemnitz granted by the Carl Zeiss Foundation to start new research group
From August 1, 2022, the Leibniz Institute for Photonic Technologies (Leibniz-IPHT) will complement its research portfolio with its new "Smart Photonics" research group. The physicist, Dr. Mario Chemnitz, is establishing his own group at the Jena-based institute over the next five years with CZS Nexus funding from the Carl Zeiss Foundation to research smart processors for modern diagnostics.
As head of the new "Smart Photonics" research group, Dr. Mario Chemnitz and his team will work on the diagnostics of the future at the interface of biology, physics and data science. The €1.5 million grant from the Carl Zeiss Foundation will enable him to build a multidisciplinary team and a state-of-the-art laboratory to develop a fully fiber-integrated smart sensor and microscopy system. At the heart of this system are fiber-integrated, neuromorphic processors that take on individual tasks from the field of artificial intelligence (AI) to autonomously recognize patterns in large amounts of data, for example on images or in signals, at lightning speed. In perspective, fiber-optic processors significantly accelerate spectroscopy and offer the potential to detect objects microscopically in a cameraless manner and to measure cells autonomously.
"I am honored to be supported by the Carl Zeiss Foundation in the CZS Nexus program. This support, but also the trust placed in me by Leibniz-IPHT to be allowed to establish and lead my own group, is a great pleasure and recognition. It shows how much potential there is in the vision of a new generation of diagnostic tools based on light-driven neural processors. I look forward to working with an interdisciplinary team at Leibniz-IPHT to conduct research on this topic in the coming years," said Dr. Mario Chemnitz.
About the CZS Nexus funding program of the Carl Zeiss Foundation
The CZS Nexus funding program of the Carl Zeiss Foundation supports postdocs on their scientific career path. The funding of 1.5 million euros enables young scientists who want to implement interdisciplinary research ideas between the disciplines of mathematics, computer science, natural science and technology to set up their own research group over five to six years."It is precisely the interdisciplinary interfaces that offer enormous potential for scientific innovation, but they don't get much of a chance in conventional funding programs," says Dr. Felix Streiter, Managing Director of the Carl Zeiss Foundation. "The Nexus program therefore consistently focuses on the connection between different disciplines."In 2022, five scientists received funding from the Carl Zeiss Foundation.
About the Carl Zeiss Foundation
The Carl Zeiss Foundation aims to create scope for scientific breakthroughs. As a partner of excellent science, it supports both basic research and application-oriented research and teaching in the MINT disciplines (mathematics, computer science, natural sciences and technology). Founded in 1889 by the physicist and mathematician Ernst Abbe, the Carl Zeiss Foundation is one of the oldest and largest private science-funding foundations in Germany. It is the sole owner of Carl Zeiss AG and SCHOTT AG. Its projects are financed from the dividend distributions of the two foundation companies.
