ICOOPMA12 Hiroshi Kudo

We had one poster presentation at ICOOPMA 2012@Nara held on June 5-7, 2012. This report provides a brief summary of ICOOPMA 2012.

This was the first time for me to attend an international conference, but I was able to attend the conference calmly because it was held in Japan. The venue, Nara Prefectural New Public Hall, is located near Todaiji Temple, and I was able to relax and give my presentation because I joined the general tourists and walked around the surrounding tourist spots before my presentation. I had expected that there would be many Japanese people at ICOOPMA since it was held in Japan, but 60-70% of the participants were from overseas, and the ratio of overseas to domestic researchers was about 7:3, with invited speakers changing every 30 minutes in the four rooms. In the Q&A session, it was always foreign researchers who asked questions, and Japanese researchers were rarely seen asking questions. In addition, there were many occasions when Japanese speakers were perplexed when asked questions by foreign speakers, and I realized once again the importance of English and the importance of participating (asking questions) in the lectures.

I gave a poster presentation titled "Fabrication of Whispering gallery Mode Cavities using Crystal Growth". I received questions from about 10 people from overseas and 5 Japanese. In the first half of the presentation, I was not able to have a sufficient discussion because I was not used to speaking in English, but in the second half, I was able to explain smoothly. Since I had concluded my presentation with the idea of eliminating the crystal plane of sapphire and making it a circle in order to improve the Q-value, many people asked me what measures I could take to make the shape of the crystal a circle. As of now, there is no data that can be inferred from my experimental results, so I would like to produce results from now on based on the information available.
The judges also seemed to appreciate my work, and I was awarded the Poster Prize. Encouraged by this, I will do my best in my research.

Noteworthy Presentations, Recent Developments

There were many presentations at this year's ICOOPMA, and here are a few that caught my attention.
In the presentation "Long-Wave Infrared-Transmitting Glasses :Optical and Electrical Properties for Sensing Applications" [Presentation No. (2C1-3)], sensing in liquid using chalcogenide tapered fibers was reported. Sensing Applications" [Presentation No. (2C1-3)] reported sensing in liquid using chalcogenide tapered fibers. The content was that the transmittance varied depending on the substance contained in the liquid and the diameter of the tapered fiber experimentally, and there were many techniques to be learned from the fact that our laboratory is related to this technology. Next, "Advances in silicon nanophotonics" [Presentation No. (3A-1)] introduced recent trends in silicon photonics, including the achievement of electro-optic modulators at 40 Gbit/s and the development of Slow light waveguides have been achieved in photonic crystals. Among them, the all-optical signal processing at 1.28 Tb/s using nanosized optical wires was especially highlighted, as it will greatly expand the possibilities of silicon photonics by linking optical fibers and optical circuits and devices. In "Recent Progress and Future Prospects of Photonic Crystals" [Presentation No. (3PL1-1)], it was reported that the Q-value of photonic crystal resonators can be freely manipulated. It was also reported that it is possible to convert sunlight into electrical energy with high efficiency by using the light emission and detection of photonic crystals. In this way, I felt that the content of this year's conference was designed with an awareness that the fusion of conventional technologies and silicon photonics will lead to a wider range of applications.

I learned many things by participating in ICOOPMA2012. Among them, I strongly felt the importance of English discussion skills. It was obvious that Japanese students, including myself, have less awareness of English than students from other countries.
