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。
