Recently, Mao Peng and Wang Zhiqiang, professors of the School of Electronic and Optical Engineering and College of Microelectronics of NJUPT, cooperated with foreign research teams andrespectively published their latest research results in Nature Communications.
Dr. Mao Peng collaborated with Professor Zhang Shuang from the University of Birmingham in the United Kingdom to publish a research paper entitled “Broadband single molecule SERS detection designed by warped optical spaces”. Dr. Mao Peng was the first author of the paper, receiving help and support from Professor Andrea Fratalocchi from King Abdullah University of Science and Technology, Professor Chen Qiang from Nanjing University School of Modern Engineering and Professor Han Min. This achievement is based on the theory of transformation optics based on the equivalent curvature of space curvature and refractive index change. It uses the inverse effect in an ingenious way, and proposes to use the curvature of the substrate to form an equivalent refractive index change, thereby enhancing the optical binding. The groundbreaking use of self-organizing template method and gas-phase nanoparticle beam combination technology has successfully completed the preparation of high-quality samples, and shortened the preparation process of samples from several hours to several minutes, providing reference for real-time high-precision detections. After the article was published, Nature Nanotechnology also published a Research Highlight entitled Curved space for fast analysis, which reported on the work.
Dr. Wang Zhiqiang and Prof. Philippe Grelu from the University of Bourgogne, France, published a research paper entitled “Optical soliton molecular complexes in a passively mode-locked fiber laser” in Nature Communications. Dr. Wang Zhiqiang was the first author and co-responding author. In his research, Dr. Wang Zhiqiang ingeniously used the fiber-mode mode-locked laser to obtain multi-pulse bound states. By virtue of DFT technique, he studied two different soliton interaction kinetics in the double-pulse bound state and the bound state. The concept of Soliton molecular complexes (SMC) was first proposed, revealing the relationship between the strength of soliton interaction and the soliton spacing in SMC. The study also further confirmed the reliability of perceiving internal dynamics of matter molecules by studying the dynamics of optical soliton bound states. That being said, this discovery is of great significance for realizing soliton manipulation and improving the capacity of fiber-optic communication systems. At the same time, it provides a new insight to the study of molecular dynamics in complex nonlinear systems.
