Outline of Research at the Start

データセンター通信用の大規模通信システムの革新のため、磁性体による独特の機能を有する二つの新しい光制御デバイスを開発する。一つめは、新構造を導入した低損失な導波路型光アイソレータを実現し高性能の光トランシーバ開発に貢献する。二つめは、磁気不揮発性により超低消費電力駆動が可能な自己保持型光スイッチを実現する。これら二つのデバイス研究を通じて光回路と磁性体を融合した磁性フォトニクスという未開拓分野を切り開く。

Outline of Final Research Achievements

In this research, (1) low-loss waveguide optical isolator and (2) self-holding optical switch with magnetic non-volatility were developed.
(1) we proposed novel isolators with mode-evolution based adiabatic structure and with ring resonator of TE-TM mode converting coupling region. Minimum insertion loss of 4.3 dB was demonstrated.
(2) MZI-based self-holding switch with high extinction ratio was demonstrated. High-speed operation of magneto-optical switch with high-frequency designed electrode under applying static magnetic field.

Academic Significance and Societal Importance of the Research Achievements

本研究では当初目標をおおむね達成する低損失型光アイソレータと自己保持型光スイッチを実現することができた。今後は他素子と集積化して機能的な光回路を形成し、「大規模光通信システム」へ実用導入することで、光通信ネットワークの大容量化と低消費電力化に貢献する。
