Recently, 2023 China's top ten advances in optics Summit Forum opened in Fuyang District, Hangzhou City, Zhejiang Province, China Laser Magazine released the "2023 China's top ten advances in optics" and held an awards ceremony. After several rounds of selection by the evaluation committee, 10 items of basic research and 10 items of applied research were selected. Among them, the achievements of Prof. Liu Xu and Prof. Yang Qing's team and the joint research results of Prof. Cai Han and his collaborators were both honored as "2023 Top 10 Advances in Chinese Optics" (basic research category). Prof. Daoyin Dai's team and the team of Jianwei Wang from Peking University, who is an alumnus of ZJU Optoelectronics (class 04 and 08), have been selected as "2023 Top 10 Progresses in Optics in China" (Applied Research Category).
The team of Prof. Liu Xu and Prof. Yang Qing from the School of Optoelectronic Science and Engineering of Zhejiang University, in cooperation with Zhijiang Laboratory, proposed a spatial frequency domain tracking adaptive beacon optical field coding method for the "major challenge" of imaging perturbations caused by mode instabilities in the motion process of multimode optical fibers, which improves the speed of motion tracking from the minute to the millisecond, and achieves the world's longest single-distance super-resolution imaging in a single fiber. We have achieved the world's longest single multimode fiber lensless, super-resolution, dynamic imaging, which is a substantial step forward for the application of multimode fiber endoscopy in life science, biology, industrial inspection and clinical diagnosis.
Cai Han, a researcher at the School of Optoelectronic Science and Engineering, Zhejiang University, and his collaborators have realized the first quantum topological manipulation of light on a newly designed superconducting quantum chip, and their constructed Fockian lattice has demonstrated a number of important topological physical models, including the realization of adiabatic transport of a topological zero-energy state in a one-dimensional lattice, and the observation of the valley Hall effect as well as Haldane fringe flow in a two-dimensional lattice. This research provides a new platform for the study of topological states in higher dimensions, bridging the gap between topological states of classical and quantum origin.
The team of Prof. Daoyin Dai of Zhejiang University's School of Optoelectronic Science and Engineering and the team of Jianwei Wang of Peking University, an alumnus of ZJU's Photonics 04 and 08 master's degree programs, have jointly developed key technologies and core devices such as large-scale photonic quantum chip modulation on silicon, on-chip multi-dimensional mixed multiplexing quantum modulation, and proposed a high-dimensional quantum entanglement self-repairing method, which can rapidly restore degraded high-dimensional entanglement in complex medium transmission, ultimately realizing high-dimensional entanglement networks with entanglement repair capability. This method can quickly restore the high-dimensional entanglement that has been degraded in complex medium transmission, and finally realizes a multi-chip high-dimensional quantum network with entanglement repair capability, which opens up a new path for the further construction of large-scale and practical quantum networks.
