Photonics4Future Lecture 3 Multi-spectral analyses of food to decrease the losses and waste: Estimating the optimal time for harvesting and consumption with a help of Photonics Abdel Karim Ruvalcaba Perez from ams-OSRAM Group Food losses and waste remain a crucial problem in modern global society. Despite policy interventions, low-middle-income countries stay at the top of production and post-harvesting losses, whereas high-income countries have highest food waste. Missing the optimal time for production and post-harvesting processing is one of the key reasons causing the losses, which is about a third of the produced food. Our study tackles this problem by focusing on the changes of spectral characteristics of food over time. The aim is to develop a low-cost spectral sensor for monitoring food condition and implementing in every step of the whole chain: from production to consumption. This enables us to choose the optimal time for processing, thus reducing food waste significantly. This contribution presents the combined effort of ams-OSRAM Group, Fraunhofer IOF, and FSU-Jena in multispectral analyses of fruits / vegetables and the influence of their constituents on the spectral characteristics over time. |

Photonics4Future Lecture 4 Hybridization in Photonic Integrated Circuits: Enhancing SiN and Si Platforms with Advanced Materials and Processes Dr. Sebastian Schmitt from Fraunhofer IOF The integration of advanced materials and processes with Silicon Nitride (SiN) and Silicon (Si) photonic platforms offers transformative potential for classical and quantum Photonic Integrated Circuits (PICs). This presentation examines the hybridization of these platforms with 2D materials, ion implantation, and electro-optic materials. The talk highlights exemplary projects on leveraging nonlinear properties of 2D transition metal dichalcogenides, electro-optic properties of non-centrosymmetric crystals, and single photon emission from implanted color centers to enhance SiN and Si PIC functionalities. In a fab-less foundry model, these integrations pave the way for innovative, scalable, and cost-effective PIC solutions underscoring the vital role of hybrid technologies in advancing the photonics industry. |

Visit W3+ Fair The W3+ fair takes place in Jena at the same time as the Photonics Days. Researchers, developers and producers from the fields of optics and photonics, automotive, information and communication technology and many more will be exhibiting there. In addition, high-tech trends, current academic research and the latest developments in the industry will be on display. This makes the fair a very good opportunity for young professionals to get in touch with leading representatives of the industry. A joint visit to the fair is therefore planned, which is free of charge as part of the Photonics Days program. More information about the exhibitors at the fair can be found here: https://w3-fair.com/en/jena/exhibitors-a-z/ You can access an overview of the lecture program here: https://w3-fair.com/en/jena/lectures/ |

Keynote Lecture & Talk Attosecond pulses of light for the study of electron dynamics Prof. Dr. Anne L’Huillier When an intense laser interacts with a gas of atoms, high-order harmonics are generated. In the time domain, this radiation forms a train of extremely short light pulses, of the order of 100 attoseconds. Attosecond pulses allow the study of the dynamics of electrons in atoms and molecules, using pump-probe techniques. This presentation will highlight some of the key steps of the field of attosecond science Vita Anne L'Huillier is a Swedish/French researcher in attosecond science. During the first part of her career, she worked at the Commissariat à l'Energie Atomique, in Saclay, France, first as a PhD student until 1986, then as a permanent researcher until 1995. She was postdoc at Chalmers Institute of Technology, Gothenburg. Sweden in 1986, and at the University of Southern California, Los Angeles, USA in 1988. In 1995, she moved to Lund University, Sweden and became full professor in 1997. Her research, both theoretical and experimental, is centered around high-order harmonic generation in gases and its applications, in particular in attosecond science. She was awarded the Nobel Prize in Physics 2023 together with Pierre Agostini and Ferenc Krausz for “for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter”. |
