CLEO 2018 Pacific Rim Seyi Kim

I gave an oral presentation on the performance improvement of photonic crystal type DeMUX fabricated by CMOS process. Dr. Noda of Kyoto University was in the audience, so I was able to successfully complete my presentation despite the tension.

During the Q&A session following the presentation, I was asked about the current losses at DeMUX. Once again, we realized that the losses are still large. In particular, the coupling loss between the waveguide and the photonic crystal is large, and improvement of this loss is essential if practicality is to be emphasized. The chairmen also asked questions such as "Is the device reproducible? and "Can this optimization method be applied to other wavelength bands? and "Can this optimization method be applied to other wavelength bands?

Overall, I was able to give my presentation in a calmer atmosphere than the session on photonic crystals at the Japan Society of Applied Physics, and I was able to respond to questions and answers without panic. It was a good experience for me to experience the level of the students of famous Asian universities at my first international conference.
