用“一束光”闯出高端仪器“国产路”

Core Viewpoint - The article highlights the successful development and commercialization of the ultra-high-resolution optical vector analysis technology by Nanjing University of Aeronautics and Astronautics (NUAA), which has achieved significant milestones in patent conversion and has been recognized as an excellent case for national patent application in 2025 [1][2]. Group 1: Technology Development - The research team, led by Professor Pan Shilong, identified a critical need for domestic high-end testing instruments due to reliance on foreign manufacturers, which posed challenges for scientific research and industrial development in China [3]. - The team developed the ultra-high-resolution optical vector analyzer using microwave photonics methods, integrating measurement functions for various optical components, which can be applied in multiple fields such as fiber optic communication and integrated photonics [5]. - The technology has achieved a wavelength resolution of 50 kHz (0.4 femtometers), a dynamic range improvement of 15 dB, and a phase accuracy enhancement of 2.5 times within a 40 GHz range, positioning China's optical vector analysis technology at the forefront globally [8]. Group 2: Commercialization and Market Impact - The transition from laboratory prototypes to commercial products faced challenges, including funding shortages and low market recognition, which the team overcame through strategic partnerships and product demonstrations [9][10]. - By 2018, the technology had successfully replaced imported high-end instruments, supporting over 100 types of high-end optical device development for major companies like Huawei and China Aerospace Science and Technology Corporation [10]. - The technology has been recognized as internationally pioneering, with 58 products achieving mass production and self-sufficiency, significantly reducing China's dependence on imported measurement equipment [10]. Group 3: Future Prospects - The demand for high-end optical devices is expected to grow with the advancement of emerging technologies such as 5G/6G communication and artificial intelligence, prompting the team to continue innovating and exploring new frontiers like quantum communication [10].
