Dear Colleagues,
Integrated photonics has witnessed remarkable development in recent years and is reshaping the landscape of modern technology. Through the high-density integration of a large number of optical components on a single chip, it has completely transformed traditional computing, sensing, and communication modes. In the field of communication, silicon photonics integration technology has become the industry standard. The commercial application of optical modules with a rate of 400 G or even higher has been achieved, significantly enhancing the efficiency of information transmission both within data centers and between data centers. In the area of optical sensing, integrated photonics-based sensors, with their single-molecule-level detection precision, have opened up new paths for early disease diagnosis and personalized medicine. Moreover, these sensors, with their high sensitivity to environmental parameters, are applied in scenarios such as real-time atmospheric monitoring and water quality analysis. In terms of technological innovation, new material platforms and heterogeneous integration technologies have been emerging continuously, enabling remarkable innovative functional applications, such as lithium niobate thin films, silicon nitride integration, chalcogenide on-chip devices, etc. The combination of two-dimensional materials and photonic crystals also brings about entirely new possibilities for the regulation of the optical field. Looking ahead, integrated photonics will continue to make breakthroughs in directions such as high-speed communication, multi-functional integration, and quantum information processing. For example, it will achieve optical interconnection at the terabit level, develop chips with integrated functions of sensing, computing, and communication, and construct stable and reliable quantum key distribution networks, bringing unprecedented innovative changes to numerous fields, including information, medicine, and energy.
