我々は高度な半導体ナノ加工技術を使ってフォトニック結晶と呼ばれる人工周期構造をシリコン等の半導体をベースに作っていますが、最近このフォトニック結晶を使って非常に小型で閉じ込めの強い光共振器を開発しました。従来、光技術は高速で広帯域な情報処理が得意ですが、電気信号に比べて閉じ込めが難しいことが弱点となっていました。我々の開発した共振器は波長と同程度の微小領域に光を1ナノ秒以上閉じ込めることができます。このような小型の共振器を使うと従来難しかった様々な光制御が可能となりますが、その一例として我々は共振器を使って光の伝播速度を5万分の1に減速するスローライトの実証に成功しています。この技術はチップ内で光情報処理を行う場合に、光信号をバッファリングしたり、相互作用増強するために使われると考えています。また、小型共振器内で光の相互作用が増強されることを利用して、超小型で超低費パワーの光ビットメモリの開発にも成功しました。これらの技術はいずれも半導体チップ内における集積化に適しており、我々は将来的に高密度に集積化された高度な光情報処理チップの実現に向けて研究開発を行っています。
