~ Self introduction, the President of the GIPO Students’ Association, 2010 academic year
~
Hi, everyone, I'm Meng-Chien Lu, a 2nd year graduate student working with Professor I-Chun Cheng. It’s my honor to be appointed as the President of the GIPO students’ association and to have the opportunity to serve my classmates and teachers. Actually, this type of service is not unfamiliar to me. I have served as the president of three students’ associations (including this term), and once as vice president. During my undergraduate study at NTU, I had been the president of the undergraduate students’ association of my department. Therefore, I'm quite familiar with the job of organizing student activities.
Taking this position is a coincidence. When I asked the chairman of GIPO to write a recommendation letter for me in early October, he told me that the GIPO students’ association needed a president. Soon after the conversation, I decided to take this offer. Therefore, much to my regret, we missed the opportunity to organize GIPO's traditional event – the Mid-Autumn dinner party. However, as Christmas day approaches, we will organize an amazing Christmas event. We appreciate the kind assistance from students’ association officers from Prof. Chih-I Wu, Prof. Jr Hau He, and Prof. Gong-Ru Lin's laboratories. We are currently working hard on organizing this party. It is our hope that we can prepare a Christmas party different from the ones in the past years, and every participatant will have a festive and merry time.
We also prepare to organize a few ball games next semester as well, so as to get students away from laboratory equipments and let them sweat on ball courts occasionally. We hope that GIPO students will meet new friends outside of their own laboratories, build good interpersonal relationships rather than focusing on their studies all the time, and identify themselves more with GIPO through these activities.
With that being said, graduate students are different from undergraduates after all. Our students’ association can only organize activities that do not interfere with students’ studies. In the mean time, every student's rule of thumb is to be responsible for his/her own studies. The students’ association will do its best to offer fun and relaxation and to become the platform for you to build connections with fellow students.
We are, therefore, looking forward to helping you live and study happily at GIPO in the coming semester. Our goal is to make you smile even during gloomy experiments. Thank you, everyone!

Christmas Dinner Party, 2010 academic year, GIPO Students’ Association
~
(Time: December 24, 2010; Location: Courtyard, 3F, Min-Da Hall, EECS, NTU)
Composed by: Meng-Chien Lu, President, GIPO Students’ Association
The GIPO students’ association and GIPO office co-hosted the Christmas party for GIPO teachers and students on December 24th to reward them for their year-long hard work and to help them get to know each other.
With the full support of Chairman Ching-Fuh Lin and Vice Chairman Chih-I Wu, we have made this party a great success; everyone who came was stuffed with food, beverages and prizes. In order to create excitement and let students get to know GIPO better, we organized the "photonics classroom" quiz with prizes. Everyone’s reaction towards this quiz was marvelous. Participants took part in the quiz by laboratories. While competing for prizes, students were also learning the history and the business of GIPO. They liked this kind of activity very much, because they would be able to interact with students from other laboratories and get to know GIPO better at the same time. Finally, the winning team happily moved the 1st prize - a small refrigerator - back to their laboratory.
The Chairman offered a special prize, which was then rewarded to a lucky and quick-to-respond student. Furthermore, we also had some other big prizes which were given out at the end of the activity. For those who didn't win any, we gave them plenty of candies as Christmas gift, which made them smile warmly in the cold winter weather. It must have still stayed vividly in everyone's heart that, during the activity, the Chairman, wishing us bright futures in the coming year, led us to shout out the slogan "advance in GIPO, our futures are boundless". Relationships among teachers and students have become closer after this party. All of us in GIPO have enjoyed a wonderful Christmas.

Everyone, replete after plenty of food and beverages, ready to answer quiz questions! |

~ The 1st Cross-Strait Forum on Optics and Photonics
~
(Time: December 6th - 8th, 2010; Location: Barry Lam Hall, NTU)
Composed by:
Wen-Ping Chen
Professor C. C. (Chih-Chung) Yang of GIPO, organized the 1st Cross-Strait Forum on Optics and Photonics at Barry Lam Hall, on December 6th~8th, 2010. There were 9 faculty members and 22 post-doctorate researchers and doctoral students from Mainland's Peking University, Tsinghua University and Nanjing University, and 15 faculty members and 24 post-doctorate researchers and doctoral students from Taiwan's National Tsing Hua University, National Chiao Tung University, National Cheng Kung University and National Taiwan University. The forum activities included lectures given by faculty members, oral and poster presentations given by students, and visits to cultural centers. Organizing this forum is a pioneering work and also a process of exploration. Based on the common but somehow slightly different languages, the participants from both sides have been looking for mutual understanding and fair treatment in the forum, and have created a good starting point for future cooperation.

~ The 1st Cross-Strait Forum on Nanophotonics ~
(Time: January 10th - 11th, 2011; Location: Barry Lam Hall, NTU)
Composed by:
Wen-Ping Chen
The 1st Cross-Strait Forum on Nanophotonics is co-organized by Professor Qihuang Gong of School of Physics, Peking University, and Professor C. C. (Chih-Chung) Yang of GIPO, NTU. It was held at Auditorium 201, Barry Lam Hall, during January 10th-11th, 2011. There were 12 Mainland scholars, from Peking University, Jilin University, Tongji University, Nanjing University, Nankai University, Fudan University, Zhejiang University and National Natural Science Foundation of China, and 14 Taiwan professors, from National Taiwan University, National Sun Yat-Sen University, Academia Sinica, National Chiao Tung University, National Cheng Kung University, National Central University and National Taiwan Normal University, delivering speeches in the forum.
Nanophotonics is one of the most important subfield of the burgeoning nanotechnology, and covers a quite broad range of topics. This forum is still at its early stage of development. After discussion, we have decided to focus the forum on surface plasmon, photonic crystal, semiconductor nanostructure and their applications. We believe this forum is helpful in promoting academic interaction and cooperation between participating parties. Mr. Shouzhu Zhang, Director of National Natural Science Foundation of China, which is similar to the position of the director of the Department of Natural Sciences of Taiwan's National Science Council, said in the closing ceremony that while Taiwan's research is more focused on the applications, Mainland's research is more focused on the basic theories. Mr. Zhang's observation may not be accurate in some ways, but he has actually identified the importance of cross-strait interactions.

Development of Si-based Nanorod Arrays
for Antireflective Application of Solar
Cells
Professor Jr-Hau He
Graduate Institute of Photonics and
Optoelectronics, National Taiwan
University
Two
novel techniques are proposed to
fabricate Si-based antireflective (AR)
nanorod arrays (NRAs). These NRAs are
designed with the attempt to enhance the
conversion efficiencies of solar cells.
The proposed techniques include: i)
reactive ion etching (RIE) combined with
colloidal lithography; ii) wet etching
with HF/AgNO3 solutions.
In the 1st technique, self-assembly
polystyrene nanospheres are used as the
etching mask for the following RIE. With
proper etching conditions, NRAs with
different geometric features can be
achieved. In the 2nd technique, the
electrochemical redox reaction between
Ag+ and
Si, and the subsequent etching effect by
HF are used to produce the NRA
structures. Compared with the
conventional quarter-wavelength AR
coating, where the reflectance only
reaches the minimum at a certain
wavelength, these NRAs exhibit superior
AR properties, including broadband
working range, omnidirectionality and
stable adhesion. The fabrication and
characterization techniques demonstrated
in our lab are expected to expedite the
development of the next-generation solar
cells. For more information, please
visit our website
