| Abstract |
PLZT位相変調器アレイと石英導波路をハイブリッド接続したチャネル数20, チャネル間隔200GHzの高速波長選択光スイッチを構成した。応答時間20ns以下の高速動作を確認した。石英多層導波路とLCOSによる大規模波長選択光スイッチモジュールを構成した。LCOSによるスイッチ内部波面補正機能を有し, 良好な波長分波, スイッチング特性を示した。高速性を有する波長選択光スイッチを活用するフォトニックノード構成を明らかにした。
The high-speed optical wavelength selective switch was fabricated with a hybrid integration of silica waveguide chips and a PLZT optical switch. It had 20 wavelength channels with 200-GHz spacing. The switching speed was less than 20 ns. We also fabricated a large-scale optical wavelength selective switch using multi-layered silica waveguides and LCOS spatial light modulators. It had wavefront compensation function and showed good wavelength switching characteristics. The photonic switching node architecture using a high-speed wavelength selective switch was proposed.
