The conference showcased a remarkable breadth of topics ranging from terahertz imaging and integrated photonics to nonlinear materials and quantum technologies underscoring the rapid pace of innovation shaping the photonics landscape. I presented my poster titled "Towards 4-dimensional Terahertz Near-Field Tomography" wherein I showed how the spatiotemporal information of subwavelength particles located deep inside sparse homogeneous samples can be retrieved using terahertz nonlinear ghost imaging. The poster sessions and technical talks provided valuable opportunities to engage directly with researchers, ask in-depth questions, and gain new perspectives on both well-established and cutting-edge areas. I found the plenary sessions particularly insightful, especially the one by Nobel prize winner Anne L'Huillier where she showed how attosecond pulses of light can be used for the study of electron dynamics.
Beyond the technical content, CLEO-Europe fostered a vibrant environment for networking and collaboration. I had the chance to connect with fellow researchers, graduate students, and industry professionals from around the world, which broadened my understanding of how photonics research is evolving across disciplines and institutions. Even casual conversations over coffee and informal interactions during the Question & Answer sessions and between presentations were surprisingly insightful. Overall, CLEO-Europe 2025 proved to be an inspiring experience that not only deepened my enthusiasm for photonics but also provided fresh perspectives and ideas to carry forward into my own research.
