Outline of Final Research Achievements

Silicon photonics attracts attention as a technique to realize optical integrated circuit contributing to speedup and densification of optical communication. Various elements including the light switch are necessary to realize optical integrated circuit. We contrived planer optical circulator using magnetophotonic crystal and tried experimental proof and characteristic evaluation. Optical properties largely changed when fabricated magnetophotonic crystal on SOI substrate. Therefore, the need of different structural design was suggested to operate as a optical circulator.

Academic Significance and Societal Importance of the Research Achievements

2次元磁性フォトニック結晶を用いた光サーキュレータに関する研究は非常に少なく，またシリコンフォトニクス技術と組み合わせた例はほとんど無い．本研究では実デバイスの形成まで至らなかったが，磁性フォトニック結晶を用いた平面型デバイスの設計に必要となる光伝搬の特徴を見出すことができたことから，今後の光デバイス研究および光集積回路の実用化に寄与することができると考えられる．
