In today's rapidly developing technology, electronic power technology and optical engineering, as important forces driving modern technological progress, are changing our way of life and work at an unprecedented speed. In order to promote academic exchange and technological innovation in these two fields worldwide, the 2025 International Conference on Electronic Power and Optical Engineering will be grandly held in the ancient capital of China, Xi'an. This conference will gather top scientists, engineers, researchers, and industry experts from around the world to explore the latest research achievements and application prospects in the fields of electronic power technology and optical engineering. The conference topics cover multiple hot topics such as wide bandgap semiconductor materials and devices, efficient energy conversion technology, smart grid systems, optoelectronic information processing technology, laser technology and its applications, and fiber optic communication and sensing technology. The conference emphasizes interdisciplinary research cooperation, aiming to promote the deep integration and development of electronic power and optical engineering through in-depth technical discussions and extensive communication platforms. In addition to traditional keynote speeches and symposiums, this conference will also feature poster displays and interactive communication sessions, providing attendees with an opportunity to comprehensively understand the latest scientific research achievements and technological trends. In addition, to encourage and support the participation of young researchers, the conference has set up a "Young Scholar Award" to recognize emerging researchers who have made outstanding contributions in related fields. This not only helps to stimulate the innovative potential of young talents, but also provides them with valuable opportunities to showcase themselves and establish professional networks. The 2025 International Conference on Electronic Power and Optical Engineering is not only a stage for knowledge sharing and ideological collision, but also an important bridge for the integration of industry, academia and research. We look forward to promoting deep cooperation between academia and industry at home and abroad through this grand event, accelerating the transformation of scientific and technological achievements into practical productivity, and jointly embracing a greener and smarter future. We sincerely invite professionals in the fields of electronic power and optical engineering from around the world to gather in Xi'an, share this technological feast, and explore the infinite possibilities brought by cutting-edge technology. Let's join hands and open the door to a new era of technology!
