Introduction:
Prof. Richard Hogg：InP materials, operating at key fibre-optic wavelengths of 1310 and 1550nm are the workhorse of the optical communications industry. This talk covers the basic materials, technologies, and manufacturing techniques for the realisation of monolithically integrated photonic integrated circuits based in InP materials.
Prof. Zinan Wang：Raman random lasing (RRFL) can be generated in the long fiber, which is beneficial for long-distance transmission of sensing information. However, remote sensing based RRFL has only been demonstrated in quasi-static scenarios due to the limitation of spectral demodulation speed. In this work, we extend the RRFL remote sensing scenario from quasi-static to dynamic, and present methods for further achieving multi-point dynamic sensing and enhancing the sensing sensitivity. This work paves the way for ultra-high-bandwidth and ultra-long-distance interrogation for optical fiber sensors.
Speakers’ profiles：
Professor Richard Hogg received this Ph.D. in Physics in 1995 from the The University of Sheffield, and then spent two years as a postdoctoral researcher at NTT Basic Research Laboratories in Atsugi, Japan. He was then awarded an EU-Japan fellowship as a visiting researcher in Professor Arakawa’s Laboratory at the University of Tokyo, Japan. He subsequently spent three years at Toshiba Research Europe’s Cambridge Laboratory, before moving to Agilent Technologies Fibre-Optic Component Operation in Ipswich, U.K., in 2000. In 2003 he joined the Electronic and Electrical Engineering Department, The University of Sheffield, where he resumed his academic career and built his group which is focused on developing the understanding of device physics and engineering, epitaxial processes, fabrication technologies and applications of various semiconductor devices such as lasers, amplifiers, superluminescent light emitting diode devices, and resonant tunneling diodes. He moved his research group to The University of Glasgow in August 2015, served as Director of Research for The School of Engineering from August 2016 to July 2018, and was appointed head of the Electronics and Nano-Engineering Division in August 2018. In 2020 he founded III-V Epi Ltd, providing custom epitaxial wafers, and Vector Photonics Ltd, who are developing photonic crystal surface emitting lasers.
Professor Zinan Wang received the Ph.D. degree from the Beijing University of Posts and Telecommunications, China, in 2009; from 2007 to 2009, he was with Alcatel-Lucent Bell Labs as a Visiting Student; from 2009 to 2010, he was with Cornell University, as a Postdoctoral Research Associate. He joined the University of Electronic Science and Technology of China in 2010, where he has been a Full Professor since 2015; he serves as an Associate Editor of IEEE Photonics Technology Letters, and a member of the Fiber Optics and Integrated Optics Professional Committee of the Chinese Optical Society. He has long been engaged in the research of information perception and laser technology, and his representative achievements was selected as one of the annually 30 most exciting optics research by the Optical Society of America; he has published >50 high-quality papers (3 ESI highly-cited) in major journals, with >3,000 Web of Science citations; he has delivered >30 keynote/invited talks in academic conferences such as OFS-25 (the flagship conference on optical fiber sensing), and served >20 times in conferences such as OECC/OSA APC/ACP; he is holding 5 US patents and 33 Chinese patents.
