At the beginning of the workshop, our president, Lin Yang, briefly introduced the research experience and outstanding works of Dr. Ning. Thereafter, Dr. Ning simply came straight to the point of the reasons why scientists endeavor in the research of nanolasers. Some applications and priorities to common lasers were enumerated by Dr. Ning followed by the roadmap and physical mechanism of the nanolasers utilizing metallic cavity. The goals of designing nanolasers were listed and the subsequent parts of the presentation were all about the arduous efforts to realize nanolasers with continuous wave operated in room temperature under electrical injection.

In the FAQs section, Prof. Sailing He and Prof. Daoxin Dai had an interaction with Dr. Ning about the physical limits of the nanolasers’ performance. Other issues, such as implementing nanolasers in visible wavelength and the idea substituting heavily doped semiconductors for metal, were raised by our members subsequently. Dr. Ning discussed and answerd questions patiently.

Both the mentors and our student members benefit a lot from the discourse of Dr. Ning and we do yearn for more such traveling lectures from OSA.

Members Attending ACP Conference

During 12nd to 15th Nov. 2013, seven members from Optical Society of America (OSA) at Zhejiang University Student Chapter attended Asia Communication and Photonics Conference (ACP) in Beijing. Through learning talks from outstanding scientists and experts and communicating with students from all over the world, we benefited much not only on academic research but also the industry opinions.

ACP is the premier conference in the Asia-Pacific region on photonics and relevant technologies including photonic materials and devices, communication and network technologies, sensing technologies, biophotonic technologies, illumination technologies, and other photonic technologies regarding energy issues. In ACP/IPOC’2013, a special symposium in memory of beloved Dr. Yingye Li was organized. As the former chair of OSA and world-known expert on optical communication, he visited Zhejiang University and fortunately gave our chapter a special visit because of the care for OSA and young researchers. Members attended the conference widened horizon greatly since we involved in different workshops on our own fields.

On 11st Nov. before the conference, the chapter held a sodality with OSA student chapter at South China Normal University (SCNU) to the Summer Palace. As one of the art treasure of Chinese Ancient Parks, the summer palace has not only important aesthetic and historical value, but also necessary ecological values. With the friendship established at last year ACP conference in Guangzhou, members from the two chapters visited the palace and discussed how to foster a one-class chapter. In the meanwhile, our members discussed some scientific topics with our friends, since we had similar but not totally same research areas.

2(A group photo for part of the members from the two chapters)

This journey to Beijing was proven to be a nice one by all accounts. We talked with scholars from different places and exchanged experiences in ideas, simulations, experiments, and so on, which turned to be an unforgettable experience to us.

It’s worth mentioning that besides the journey in Beijing, Hongyan Liu, secretary of the chapter visited to Tianjin and gave a conversation with the students from Tianjin University who would like to form an OSA Student Chapter in their university. She introduced the status of chapter at Zhejiang University, the procedure and essential condition for a new OSA student chapter; what is more, she shared her experience in organizing activities patiently. Considering the enthusiastic students were sophomore students, lack of sufficient professional knowledge and laboratory support, she suggested them to build up a close cooperative relation with the chapter at Nankai University located next to Tianjin University, and also kept in touch with our Zhejiang University chapter for further help and longtime relationship.

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.

7(A group photo for part of the members of ZJU chapter & NJU chapter)

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.

10(Nanjing Tour)

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.

Step out Labs and Make a Different Understanding of Industries & Scientific Research

—- visit to Shanghai of OSA Student Chapter at Zhejiang University

In awaken spring, during 19-20 Mar. 2013, the student chapter of OSA at Zhejiang University organized a visit to “LASER World of PHOTONICS” in Shanghai. About twenty members of the chapter attended the exhibition. We also had the chance to visit the “Shanghai Institute of Optics and Fine Mechanics of Chinese Academy of Science (SIOM)”, and polish a happy & fulfilling exchange with the OSA student chapter at SIOM.

1(A group photo for all the attendees for the exhibition)

“LASER World of PHOTONICS” is the world’s leading trade show for optical technologies. Since 1973, it has taken place every two years in Munich, Germany. “LASER World of PHOTONICS” is the leading regional trade show for optical technologies in CHINA.

With the new World of Photonics Portal, the new information and networking platform for the photonics industry, Munich International Trade Fairs addresses the industrial and scientific communities and users of optical technologies, giving them an excellent opportunity to exchange information. The platform provides the virtual photonics community with information about events and covers the topics Business Life, Market, Products and Business Club. Participation are mostly industry renowned manufacturers, such as TRUMPF, Rofin, Staubli, ABB, Zeiss,Olympus, and so on. Many company’s products are often used in our experimental process, like the laser of the Coherent Company, microscope of Olympus.

As soon as we arrived at the halls, members could not wait to have a close look at the various new technologies and products. The exhibitioners are divided into four parts according to their research field. The many latest technology and products make everyone amazing, especially the laser processing industry. Sophisticated processing technology, unique style, warm customer negotiations atmosphere, all these let our members find everything new and fresh. Different from often staying in the laboratory, the exhibition makes us closely feel research and operation of the enterprise, what’s more, it enhances our confidence in our photoelectric industry.

The students showed high enthusiasm during the 2-hour-long visit, and the plentiful products & latest technologies used in industry seemed to draw a lot of their attention that many members were late for the deadline to get together. Although we reluctantly left the show, but the discussion still continues, the shock of the enterprise and introspection on our own scientific research also continues.

2(Some members are waiting for assemble)

As planned, we went to the SIOM to have a friendly visit in the next day. The students there gave us a warm reception and showed us around their laboratories. The research of High Power laser and Physics test device, named “Shenguang”, was mainly introduced by the host, which shocked us deeply and attracted some members to have a deep talk with the researchers there. With their accompaniment, we also visited State Key Laboratory of High Field Laser Physics. The researchers in SIOM and us reached a consensus to have more cooperation in academic exchange.

According to their introducing, ShenguangⅡ high-power laser experiment device is the domestic first platform of large laser device related experiment ability, and the Shooting Range System is most closely combining the physics experiments & physical diagnosis, which has been honored as “the engineering of making an little artificial sun a big on earth “. In 2012, the technique won the the integrated operation of science and technology award of Chinese academy of sciences major infrastructure running annual meeting. In visit, our members and researcher there discussed deeply at the institute of physics experiment requirements, specific requirements of laser and drive units, etc. After the meeting, the two student chapter chairmans: Lin Yang and Shuang Liu introduced both basic situation, and learnt activity ideas from each other. Yang said:” We student chapter should make our most efforts to strive for growing communication platform of different student chapter, design activities creatively and meaningfully. Our only goal is to service our all members wholeheartedly.”

The members came back to Zhejiang University in the evening of 20 Mar. 2013. In spite of the exhausting journey, we all look forward to the exhibition next year to broaden the vision of our field, especially the technologies from the top companies. Also the visit to SIOM gave us a chance to get in touch with the research institute of CHINESE SCIENCE ACADEMY, which may have a different operation mode from the universities.

This activity is the first in this year, our members evaluate it making sense. Believe that following activities for our members and the students in the center will provide more communication opportunities, and create even greater value for all.

Mobilization conference about the project of investigating the History & Developments of Photonics

On Jan 5, 2013, the OSA Student Chapter in Zhejiang University held a mobilization conference about the project of investigating the History & Developments of Photonics, in the Greenroom on the first floor. Xiaowei Guan, the former President illustrated the specific plans and requirements for future development, and the details were discussed subsequently. The seminar aimed at clarifying the tasks and goals of the project by means of unrestricted discussions.

The meeting started at 1 o’clock. Xiaowei Guan firstly reported the contents of the seminar. As researchers in the field on optics and photonics, the members have always been looking for chances putting our scientific outcomes into applications. All the members in the project are divided into four parts named Group A, Group B, Group C & Group D. Group D mainly study the research status and outcomes of the world’s top research groups. The other three groups concentrate on optical communication, and Group A on devices, B on the backbone network system and C, the access network system specifically. All the selected companies to be investigated are the outstanding representatives in the field such as IBM, Intel, Huawei so on and so forth.

(A member from Group A is introducing their topic background)

The next time Xiaowei Guan made a brief introduction to the initial rough plan of each groups. As the leader of Group C, he divided the members into three parts: components & devices, networks and applications, based on the crew’s personal background. Then Xiaokun Wang, the leader of Group A, reported his considering ideas: investigating the past, present and future of the two companies (Intel & IBM); or grouped according to the scientific research and engineering applications by a combination of the two companies. During the discussion, some members advised him to add the institutions in cooperation with IBM & Intel, which can be helpful to get a deeper knowledge of photonic integrated technology. After analysis of the pros and cons, finally division by the overall and detail of the two companies were decided. The next Group D packet was very simple, according to the crew’s different research fields directly correspond to the appropriate direction of the world’s top research teams. The last Group B leader Lingchen Huang also raised their three grouping base: enterprises, network or technique, and the first method was selected after fierce discussion.
