    Looking back at iNOW 2023


    On 27 July 2023, the closing ceremony of the international Nano-Optoelectronics Workshop 2023 (iNOW 2023) – hosted by the Chair of Applied Physics in Würzburg – was held at the Bürgerspital Weinstuben. On this evening, poster prizes were awarded to the student poster presentations of outstanding quality. The chair holder of the Chair for Applied Physics, Sven Höfling, who co-chaired the workshop with Alfred Forchel congratulated the winners and looked back on the past two conference weeks.

    The iNOW 2023 participants and guests at the conference venue (Neubaukirche).

    During the international Nano-Optoelectronics workshop 2023 (iNOW 2023), brilliant minds from around the world had shared cutting-edge insights into their research, breakthrough discoveries, and transformative technologies that shape our world: 57 scientific talks, 4 industry talks and 2 editorial talks were held, and 40 poster contributions were made. Over the course of the conference, through keynote speeches, panel discussions, workshops, and presentations, ideas were exchanged in thought-provoking conversations and new collaborations initiated that pave the way for future advancements. 170 participants and guests seized the opportunity to participate actively in the sessions, to learn from each other, and to connect with professionals, researchers, and industry leaders from around the globe.

    Through lab tours, insights were given into the research of the Chair of Applied Physics of the University of Würzburg. The participants also had the chance to enjoy Würzburg and its surroundings and learn about the rich history of the region. In various excursions, they got to know the homes of former Prince Bishops, Würzburg Residence, which is UNESCO world culture heritage, and Marienberg Fortress. At the weekend, they visited Rothenburg, the Church Fortress Museum in Mönchsondheim as well as the beautiful castle and court garden in Veitshöchheim and immersed themselves into the Franconian cuisine.

    Topics at iNOW 2023

    We are happy that many scientists of ct.qmat have contributed directly to the workshop with their talks as invited speakers, which has been a prolific stimulation to many discussions.

    The scope of iNOW 2023 covered a variety of topics ranging from fundamental physics to state-of-the-art applications of optoelectronics phenomena such as:

    • Photonics and society: photonic devices for life sciences and environment
    • Lasers and Applications
    • Topology and PT Symmetry
    • Integrated photonic (quantum) circuits
    • Photonic crystals
    • Epitaxy and processing: Synthesis, growth and characterization of advanced materials
    • Nanowires: technology and devices
    • Nanodevices
    • Physical properties of photonic nano/atomic systems
    • Quantum Information
    • Commercialization
