Focus on Micro-nano Photonics

– Academic Visit to Nanjing of OSA Stu. Chapter at ZJU

During 28th July and 1st Aug. 2013, although Hangzhou was intolerable warm, our students were still full of enthusiasm. Optical Society of America (OSA) at Zhejiang University Student Chapter organized the “Nanjing academic visit” activities, and 27 members from our chapter participated actively. As one of the few invited groups by College of Engineering and Applied Sciences Engineering quantum electronics and optics at Nanjing University (NJU), OSA student chapter at Zhejiang University (ZJU) participated “Micro-Nano Photonics and Applications” in 2013 National Doctoral Forum organized by Nanjing University, and organized friendly joint with OSA student chapter at NJU. The event mainly aimed to provide an academic exchange platform high-level and wide-ranging for the participants, broaden academic horizons and stimulate creative thinking, which totally encourage members to make more influential scientific researches as soon as possible.

With the arrangement of the previous day, at 9:00 a.m. on the 28th, 27 members from Center for Optical and Electromagnetic Research of ZJU congregated and took a group photo at East BLDG #5, Zijingang Campus, and then went to Hangzhou East Railway Station together. Along the way we felt very excited, the bus is also unimpeded. Through precise calculation by the President, an hour’s drive guaranteed the smooth arrival. We took the recently opened G7670 train to Nanjing. At 2:00 p.m., under the leadership of the President of OSA Student Chapter at Nanjing University, we went straight to the Gulou Campus, and registered for the conference, made accommodation, all arranged by the organizers in perfect order.

On 28th night, according to the arrangements, we visited the National Laboratory of Solid State Microstructures (NLSSM) of NJU. NLSSM was established in 1984, among the first group of state key laboratories established in China. As a fundamental research laboratory, the missions of NLSSM are to design and fabricate new artificial microstructured materials via designing and tailoring the energy band structures in reciprocal space, find out new macroscopic and microscopic quantum effects and principles, develop new theories and methodology based on quantum physics, and endeavor to meet the scientific challenges and technological requirements encountered in the post-Moore era and the post-petroleum era. The host organized graduates familiar with the laboratory to do a detailed introduction. The laboratory published in “Nature” published for the first time, to achieve a breakthrough, followed by three papers in “Science”. From 2000 to 2005, great progress has been made with 37 papers in “Phys. Rev. Lett.”. We impressed greatly with these statistics, and made up our mind to pursue greater breakthroughs. The visit lasted about two hours, and we learned a lot, from a broad selection of academic orientation to specific experimental study.

“Micro-Nano Photonics and Applications” Doctoral Forum was officially opened in 29th. As invited guests, the main tasks of our participants were including two parts: make a report and listening to reports. Report was relatively easy and pleasant to listen to, you can understand, or completely do not understand, but should be active to ask questions. How much you learnt depended on your knowledge acquired and reporter’s speech skills.

The forum invited Prof. Zhang Xiang from the American Academy of Engineering, Prof. Xiao Min from Nanjing University, Yuan Xiaocong from Nankai University Professor, Prof. Zhou Zhiping from Peking University, Prof. Tong Limin from Zhejiang University, Prof. Li Zhiyuan from Chinese Institute of Physics, Prof. Xu Hongxing from Wuhan University. This day, the celebrity’s report was the highlight of this trip, and a full day’s reports were spiritual feast. In particular, Berkeley Prof. Zhang Xiang, was as famous as his technique: negative refraction – “invisibility cloak”. And Prof Zhang team’s development model and research areas were both related to our team, which attracted most our members. Prof. Zhang had been committed to the preparation of micro-nano structure, characterization and physical device design; the ultra-structural material, surface plasmon laser science, optical frequency conversion optics and other areas. He developed the first surplus lens, whose resolution of optical imaging was beyond the diffraction limit for the first time. His research group made prominent contributions in the field of micro-and nano photonics. We were impressed and inspired by his innovative thinking, rigorous and in-depth theoretical analysis, which set our team a good academic example.

In the evening of July 29th, a grand workshop was organized. The invited professors are not only giants on scientific research, but also some international journal editors and life guide. The most difficult in life was to make choices at the various crossroads, and most topics were around the word “choose”. It was good to do research at home or on broad, to work or to do research, series of such questions were asked and answered patiently. The editor teachers also shared their review insights for article writing. Congratulations to their success, and we looked forward to their future more brilliant! Meanwhile, we hoped more people inspiration and encouragement to realize their glory!

End of this fraternity, OSA student chapters in ZJU and NJU held in a simple friendship. The members exchanged of academic acquaintance, living in Nanjing and Hangzhou. The new Chairman of NJU chapter made in-depth conversation with the present and the former Chairman of ZJU, which lasted for over two hours.

On 30th, there was the second main process of academic conference: students group reports. The former chairman Xiaowei Guan gave up his usual witty style, but made the colleague audiences interested only use expertise. The presentation was relaxed, but also technical. In the subsequent competitions, member Xiaowei Guan and Fei Ding won oral presentation and poster Excellence Award respectively. At the closing dinner in evening, Chairman Lin Yang as the only doctoral representative made a speech and thanked the organizers and OSA student chapter at NJU, expressed congratulations to the success of the forum. Finally, we presented homemade souvenirs to the friendly chapter, on which the acrostic won warm applause.

There was Nanjing one-day tour organized by NJU on 31th. The former Presidential Palace located in ancient Nanjing was our first destination, which have become the largest modern history museum. We also visited Mausoleum of Sun Yat-sen and Qinhuai River.

We continued to stay one night and returned back to Hangzhou on 1st Aug. Five days of academic visit to Nanjing came to a successful conclusion.

In summary, the doctoral forum makes sense. Firstly, through understanding of related study groups from different schools and institutes, we can learn their strengths and find our advantage, and more importantly, not only broaden our horizons, but also enhance the determination and confidence to make world-class research. secondly, the good friendship with NJU OSA student chapter lays foundation for future cooperation. Third, the all members said had enhanced lots on both academic and experience, and enjoyed.

This four-day visit is a milestone event in our chapter’s academic activities, and all participants learn a lot. It’s believed there will be more opportunities for our members and students in COER to exchange and communicate in academics. More efforts and greater value will be made for us to step out labs and others to come to our chapter.
