    京都大学 大学院 工学研究科 電子物性工学専攻 コンピュータのネットワーク化、並列処理化に伴い、データ伝送の大容量化が望まれている。垂直共振器型面発光レーザ(VCSEL)は面に垂直方向に発光するため、現状の端面発光レーザに対して二次元集積性に優れ、大容量データの並列伝送を可能とする技術として期待されている。本研究ではVCSELの利点を生かして実用化するために駆動電圧上昇の問題をメサ光閉じ込め構造の導入により克服し、光情報処理に必要な発光、受光、スイッチ、メモリ、光増幅機能を集積一体化した面発光機能素子を実現した。また、並列データ伝送への応用を目指した2次元VCSEL伝送モジュールとその並列性を生かしたVCSEL光スイッチの開発を行った。
