On July 11, 2026, the 2026 6th International Conference on Optoelectronic Information and Communication Technology (ICOCT 2026) successfully concluded at Capital Normal University. The conference brought together more than 100 experts, scholars, and engineering technicians from domestic and international universities, research institutes, and enterprises. Through keynote speeches, invited talks, oral presentations, poster displays, and integrated online and offline exchanges, participants held in-depth discussions on the latest advances and future directions in the fields of optoelectronic information and communication technology, injecting new vitality into cross-disciplinary innovation in optics and communication technology.

This conference was jointly hosted by Capital Normal University, Beijing Jiaotong University, and Beijing Information Science and Technology University, organized by the Key Laboratory of Terahertz Optoelectronics of the Ministry of Education, and co-organized by Chengdu University of Technology and the School of Optoelectronic Science and Engineering of Changchun College of Electronic Technology. The conference adopted a combined online and offline format and attracted scholars and enterprise R&D personnel from many universities and research institutes across the country. The on-site academic atmosphere was strong, and exchanges were lively.

The opening ceremony of the conference was chaired by Researcher Zhang Liangliang, Director of the Department of Physics at Capital Normal University.Professor Song Jun, Member of the Standing Committee of the Party Committee and Vice President of Capital Normal University, delivered a welcome speech, extending a warm welcome to the experts and scholars who had traveled from afar. He introduced to the guests the development achievements of Capital Normal University in the field of optoelectronic information and communication technology, emphasized the core role of optoelectronic information and communication technology in promoting next-generation information technology, integrated space-air-ground-sea networks, and intelligent sensing systems, and called for strengthened international scientific research cooperation and industry-university-research collaborative innovation.

The keynote report session was chaired by the co-chairs of the conference, Professor Zhang Cunlin of Capital Normal University and Professor Gong Yandong of Beijing Information Science and Technology University. Four top scholars were specially invited to give keynote reports .Professor Wu Chongqing of Beijing Jiaotong University deeply explored the complex comprehensive behavior of optical waveguides under the combined action of multiple polarization effects and proposed an innovative method of transforming matrix problems into the quaternion domain; Professor Wu Jian of Beijing University of Posts and Telecommunications proposed a joint compensation scheme of adaptive optics and mode diversity reception to address the key challenge that satellite-to-ground laser communication is susceptible to atmospheric turbulence; Professor Yu Xia of Beihang University reviewed laser-maintained plasma broadband light sources, analyzed the influence of optical path design on plasma, and looked forward to their applications in detection and imaging; Professor Zhang Yan of Capital Normal University proposed optically addressed metasurfaces for dynamic control of terahertz wavefronts, providing a reconfigurable platform expected to become a key future terahertz technology.

The afternoon agenda of the conference was chaired byAssociate Professor He Zehao of Capital Normal University, and included invited reports, oral presentations, and poster displays. The invited reports were delivered byAssociate Professor Hu Guoqing of Beijing Information Science and Technology University and Senior Engineer He Jingwen of Beijing Jiaotong University, who shared their research results. The oral presentations were given in turn by young scholars from Beijing Institute of Technology, Beijing Information Science and Technology University, Capital Normal University, Wuhan Donghu University, Anhui Polytechnic University, Beijing Institute of Control Engineering, and other institutions. The topics covered frontier directions such as single-cavity multi-dimensional multiplexed fiber lasers, tunable terahertz wavefront metasurfaces, self-powered broadband heterojunction photodetectors, physics-informed neural networks, terahertz programmable modulators, photonic crystal chiral bound states in the continuum, mid-wave infrared polarization imaging metasurface design, multimodal gait recognition, aerospace fiber-optic rotary transmission systems, and lithium niobate on-chip power splitters. On-site interaction was active, and questions were in-depth, fully demonstrating the innovative vitality of young researchers.

In addition, many high-quality poster papers were displayed during the conference, with research topics covering optoelectronic information processing, communication technology, terahertz technology, and optical devices. Conference representatives held lively discussions during coffee breaks, promoting the achievement of cross-disciplinary cooperation intentions.

The successful holding of ICOCT 2026 would not have been possible without the enthusiastic participation and strong support of every attendee. We thank all the experts, scholars, young researchers, and conference organizing staff who came from afar for their hard work. The conference focused on the most cutting-edge technological advances and future development trends. We sincerely invite colleagues in the global optics and communication technology community to continue to follow and support ICOCT, jointly explore the future of science and technology, and promote the sustained progress and development of the industry!

Let us meet again in 2027, gather once more, and jointly celebrate another grand optoelectronics event!
