Tell You a Story about Light, Different from the Textbook

– Youth Education Activity of OSA student chapter at Zhejiang University

On July 8th 2015, the OSA student chapter at Zhejiang University organized a youth education activity, inviting some of the first-year students from Hangzhou Changhe High School (http://www.hzchgz.cn/). Most of the students came from poor families, who had less education resources. Our event aimed at providing access to interesting and basic optics knowledge, meanwhile inspiring them to explore in the field of optics. The event was also supported by SPIE and IEEE student chapter at Zhejiang University.

 The event was divided into 2 parts. Lectures delivered by our members gave the students a first glance of optics. Then the students were engaged in the experiments to gain practical experience of optical research.

The lecture began at 12:00 a.m. in the conference room of our center. Senling Zhang, an OSA member, gave a brief introduction to the college of optical science and engineering, along with the major of optical engineering. Jun Yuan, the president of IEEE student chapter at Zhejiang University, gave a talk about the development of optics. Christian Huygens, Isaac Newton, James Clerk Maxwell and Albert Einstein were introduced with their fundamental theory and great contribution. Students obtained a rough picture of optics through these lectures and some basic knowledge they might use in the following experiments.

After lectures, students were divided into 10 groups, taking turns to join the different experiments. For each experiment, one member was in charge of explaining the principle, demonstrating the operation and instructing students to finish it by themselves. We had designed 9 basic experiments shown in the following table.

 With the instruction of our members, students understood some basic optical theory through interesting and visualized experiments, which gave them a deep impression. Most of the students were so deeply attracted by different experiments that some students even did not want to leave after the gathering time.

Through this event, our chapter enhanced our friendship and long term cooperation relationship with Hangzhou Changhe High School. We shouldered our responsibility of youth education, spreading optics knowledge to more young students. Our members practiced their skills of presentation and communication with teenagers during this event.

Enrich Your Understranding of Science & the Light

– Youth Education activity of OSA Student Chapter at ZJU

On Jan. 1st 2015, the OSA student chapter at Zhejiang University organized a communication activity with teachers and students in Changhe Senior High School (http://www.hzchgz.cn/) located in the outskirts of Hangzhou city, aiming at sharing the studying experience and life in high school and the university, meanwhile give them an introduction to the Optical Engineering and basic optical knowledge. Twenty of us arrived at the school at 2:30 p.m. We have a meeting first to assign our members to different classes.

IMG_0922(Members are being trained to communicate with high school students)

The whole activity was divided into two parts. One was a psychological training program which was a new part this year, and the other was in-class lectures focusing on two different topics. One of the topic was to share the study experience and information of Optical Engineering and the other was concentrated on the psychological health, including teaching them to reduce the pressure during the study and examination, which is also a new topic this year.

During the psychological training activity, we had a training program to reduce the pressure during the preparation of coming College Entrance Examination, meanwhile increase their energy and concentration. Two students were picked up from every class and were divided into 4 groups. After an interactive game, everyone joined in and our members got familiar with each other immediately. Then, the students were encourage to give a talk about how to prepare for the College Entrance Examination at the subject which they were good at. At last, we give some demonstrative experiment of optics using optical suitcase, in which students had been excited from the interesting phenomena. Xiaoyan Wang, the former president of OSA student chapter at Zhejiang University, together with Borui Li, another member of OSA, distributed the equipments in the optical suitcase to the students. With the help of equipment, they explained the polarization, dispersion, diffraction of light to these high school students. Everyone was attracted by the interesting experiment and their vivid explanation. They were not willing to leave even when the time was up, so that the activity was extend for extra 20 minutes.

IMG_1111(The group photo of the participants in the psychological training activity)

For the in-class lectures, our members were distributed to each class. We did not determine the content of the lecture, require members to concentrate on the topics we had mentioned above. As an example, Xiong Yang mainly introduced to these students about the colorful life in the university, in order to encourage the students to work hard and get enrolled by their dream universities. Shipeng Wang focused on his own experience during the study in high school. He suggested that students should not only engage themselves in the sea of examination papers, but also summarize and introspect themselves immediately after the exams. Keqi Ma and Penghao Liu introduced the optical knowledge and the Optical Engineering which we majored in to the students. There was a Q. & A. session after each lecture. Students from Changhe High School were so eager to ask all kinds of questions from the study in high schools and life in universities that some of our members even missed our time of gathering.

IMG_1075 1(Xiong Yang was talking about the life in university and Keqi Ma was explaining the periodic table of elements)

Through this activity for the Changhe Senior High School, the students had expanded their horizons, particularly in the Optical Engineering. They were highly encouraged to work hard for the coming University Entrance Examination, and were taught methods to solve the problems and overcome the problems they might met in the future. Our members also established the contact with the students, so that the students can get help after the activity was over. We are looking forward to cooperate with the members at Changhe Senior High School next time.

Every student in Changhe Senior High participated in the activity were asked to fill in a questionnaire to give a feedback to our activity. Almost every student was satisfied with our activity and was willing take part in again. More results of the questionnaire will be shown on our website.

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.

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.

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

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.

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.
