The Front
FromNovember 18 to November 24, 2019, led by Doctor Ding Mingfei, chairman of theAmerican Optical Association (OSA) Zhejiang University Student Branch, fivesenior doctoral students from the College of Optical Science and Engineeringcarried out a week-long visit to The University of Tokyo and Osaka Universityin Japan. Thestudents visited the Advanced Photonics Research Center (PARC) at OsakaUniversity, the Advanced Science and Technology Research Center (RCAST) and theInstitute of Production Technology (IIS) at the University of Tokyo. This visitnot only conducted business exchanges between OSA chapters, but alsostrengthened the connection between the two famous universities and ZhejiangUniversity through laboratory visits, seminars, lectures and other richacademic activities. This exchange also expanded the academic vision andexercised the academic communication ability of doctoral students.
Visit toOsaka University
Osaka University is a top-rankedand world-class well-known research comprehensive national university withheadquarters in Osaka Prefecture, Japan, and Japan's third highestcomprehensive strength. Founded in 1931, Osaka University is one of Japan's topuniversities, and enjoys a high reputation worldwide. In the 2020QS WorldUniversity Rankings, Osaka University ranked 71st. Osaka University is auniversity with strong research capabilities in the field of optoelectronics inJapan.
Haneda Suita Campus Engineering College Building
Osaka University PhotonicsAdvanced Research Center (PARC) is Japan's leading photonics science andindustrial research center. Since the establishment of the center in 2007 byProfessor Satoshi Kawata, a well-known Japanese photonics expert and OSA 2020vice chairman, the center has been engaged in nano-photonics, surface plasmonphotonics, biophotonics, multiphoton lithography, nanomaterials and otherfields involving chemistry, physics, biology, materials, and devices haveopened up remarkable achievements, enabling Japanese scientists and engineersto lead the photon revolution in the 21st century together with others aroundthe world.
On November 20, the visiting groupcame to the Suita Campus of OsakaUniversity to starttheir visit to PARC. Under the warm reception of Shunsuke Maeda, Chairman ofthe Osaka University OSA Chapter, the visiting group first went to theDepartment of Applied Physics to visit Professor Fujita's research group. Fujita Lab is mainly engaged in basicand applied research in the field of nano-photonics such as super-resolutionimaging, Raman fluorescence imaging, multiphoton imaging, etc. Maeda introducedthe main research team of the Department of Applied Physics and the mainsituation of PARC. Afterwards, the visiting group visited the clean room wherethe super-resolution imaging platform is located, and also learned about theircutting-edge application research in cancer diagnosis and imaging.
In the afternoon, Professor Zouheir Sekkat made a speech,he expounded the research progress in the field of nano-photonics in detailfrom the aspects of thin film photovoltaics, two-photon micro-nano processing,plasmon enhanced photochemistry, and plasmon coupling in metals anddielectrics, and discussed future prospects for optical and photonics research.Professor Fujita was then invited to give a special academic report for half anhour. Professor Fujita is a well-known scholar in the fields ofsuper-resolution and Raman imaging. He introduced the research results andprogress of the research group in the fields of super-resolution imaging andRaman imaging in recent years. Starting from the basic principles ofsuper-resolution imaging, he described the research work in simple terms aroundworking on principle expansion and system improvement around core issues suchas how to obtain enhanced image contrast and increase resolution.
After the meeting, members of bothsides eagerly communicated and posed for a group photo.
Visit to Osaka the University ofTokyo
The University of Tokyo is aworld-renowned research-oriented comprehensive national university withheadquarters in Bunkyo, Tokyo, Japan. As Japan's highest academic palace and the first ofseven old imperial universities, it enjoys a high reputation all over theworld. In the 2020 QS World University Rankings, the University of Tokyo ranked22nd.
The Advanced Science andTechnology Research Center (RCAST) of the University of Tokyo contributes tothe development of science and technology by quickly responding to newchallenges brought about by scientific development and simultaneous changes insociety. RCAST was founded in 1987 topractice the fusion of science and art in a wide range of research fields,including information, environment and energy, materials, chemical biomedicine,accessible research and social sciences. The research center has more than 40laboratories of the same name in a wide range of professional fields. They areconducting advanced research in science, technology, and social science andtechnology, as well as barrier-free research fields, and extending theseresearch fields from basic and applied fields to social systems. A wide rangeof areas.
On the morning of the Nov. 21st, the delegation arrivedat the University of Tokyo's Komaba campus and began their visit to RCAST.During the RCAST visit, the students were warmly received by Huang Yunpeng, theperson in charge of the OSA East Branch. We first went to the center'sYamashita-Set laboratory for a simple visit and exchange. The research team hasa high reputation in the fields of fiber mode-locked lasers, OCT imaging andother fields. In the afternoon, Ding Mingfei briefly introduced the generalsituation of the OSA Zhejiang University Chapter, and expressed sincere thanksto the team teachers and students for their reception and arrangement. ThenSet's group arranged two doctoral students, Zhang Chao and Zhang Zheyuan, tomake wonderful reports on "Mode-lock Fiber Laser" and "3D LaserScanner and GAWBS", respectively. After that, Yin Taoce and Chen Qicombined their research directions to bring the research of "FiberLaser" and "Widely Tunable Optical Transmitter Using an IntegratedV-Cavity Laser and Mach-Zehnder Modulator" to the teachers and students ofthe Yamashita Set Lab, which aroused strong interest and heated discussionsamong the participants.
After the seminar, the visit group was invited to attendthe RCAST lecture. At the meeting, Professor Ryohei Kanzaki, Executive Directorof RCAST, introduced the development of the Institute to the participants indetail. He talked about the historical origin, mission and vision, researchdirection, future layout, important breakthrough results, and futuredevelopment concepts of the Institute, making people fully feel that thisresearch center is based on the University of Tokyo and is committed to solvingthe future extremely challenging interdiscipline of humankind. The goal ofRCAST is to provide the core impetus for achieving the Sustainable DevelopmentGoals and creating an inclusive society.
The University of Tokyo Institute of ProductionTechnology (IIS) is the largest comprehensive industrial technology instituteat the University of Tokyo. Currently, IIS includes five research departments,one chairperson, four company-sponsored research programs, six socialcooperation programs, seven UTokyo IIS research centers, one IIS researchcenter, two cooperative research centers, and one international cooperativeresearch center, Chiba Experimental Station, Design-Led X Platform, Utilitiesand Administrative Office. These research departments of IIS conduct basicresearch activities in various research laboratories, carry out extensive andin-depth collaborative research together, and work closely with researchersfrom different disciplines. In particular, project research activities arecarried out in research centers, and the entire research organization issupported by public facilities and administrative departments. IIS has many researchareas and covers almost all areas of engineering disciplines, from micron andnanoscale (such as quantum level) to large scale (such as global level andspace). IIS is one of the largest university-affiliated research institutionsin Japan.
On the 22nd, the visit group started visiting theUniversity of Tokyo IIS. Theyfirst came to the laboratory of Professor Yasuhiko Arakawa under the IIS.Professor Arakawa is an authority in the field of quantum dot lasers and thedirector of the IIS nanoelectronics Center. The students went to the clean roomof Arakawa Lab under the leadership of Dr. Feng Tian, special assistantprofessor in the group of Professor Satoshi Iwamoto.
