I gave a poster presentation at CLEO/EUROPE2013 (Conference on Lasers and Electro-Optics Europe 2013) held in Munich, Germany from May 12 to 16. This was the first time for me to visit Germany. Although it was only a short stay of about one week, I fell in love with Germany because of its safety, cheerful and friendly people, beer, etc. I heard that there are many similarities between Germany and Japan. I had heard that Germany has many similarities with Japan, and it was no wonder. If I have a chance to study abroad in the future, I would like to choose Germany.
CLEO/EUROPE (Conference on Lasers and Electro-Optics Europe) is a sister conference of CLEO, which is held annually in the United States. The main topics of discussion at the conference were fundamental research fields such as quantum optics, nonlinear optical phenomena, and lasers, and I got the impression that the number of presentations on applications such as silicon photonics was low. I was very disappointed that the number of presentations related to micro optical resonators such as photonic crystals was also very small, as I am a specialist in micro optical resonators, but I think it was meaningful to hear presentations on research outside of my specialty that I am not usually exposed to.
The Laser World of Photonics, an exhibition held in conjunction with the conference, is an indispensable part of CLEO/EUROPE. The exhibition was very large, and the four main halls were filled with booths of many companies. It would not be an exaggeration to say that "the conference is attached to the exhibition". In addition to manufacturers of optical equipment for experiments, companies that handle products for industry, such as metal processing machines using lasers, also exhibited, indicating that the exhibition targets not only the academic world but also the industrial world. It was also very interesting to see a group of Chinese companies exhibiting under the title of "Made with China," which gave us a glimpse into the strategic overseas expansion of Chinese companies.

The poster demonstrated wavelength control of silicatroid microcavities by additional laser reflow. Although the results were still rough and not very controllable, I gave a presentation in the hope that the audience would be interested in this aspect, since no research method has been proposed to permanently change the resonance wavelength of silicatroid micro optical resonators. Most of the audience had little prior knowledge of silicatroid micro optical resonators, so I could only give basic explanations of the fundamental principles and results of silicatroid fabrication and wavelength tuning, and could not engage in in-depth discussions. However, they seemed to regard the poster presentation as an opportunity to learn something new about an unknown research field, which is something we should learn from their attitude.

Lastly, at last year's CLEO, I was afraid to participate in the poster session because I was not confident in my English ability, but this year, although I had some communication difficulties, I felt that I was able to discuss my poster and others' posters well. The poster session is a good opportunity to discuss with researchers from around the world on an equal and casual basis, so I would like to continue to improve my English communication skills and make more use of the poster session.
