| Abstract |
モノリシック構成で多チャネル位相変調器を有するPLZTモノリシック可変波長フィルタの設計・試作を行った。フィルタのクロストークは、TE偏光において-14 dB、TM偏光において-13 dB、3 dB帯域幅は、TE偏光、TM偏光どちらも110 GHzであり、応答時間40 ns以下の高速動作を実現した。光スペクトル制御回路の制御方法を検討し、振幅スペクトル制御では、任意の中心波長で帯域可変動作が可能なことを確認し、位相スペクトル制御では、可変遅延動作を実現した。また、石英アレイ導波路回折格子とPLZT位相変調器アレイを集積し、スイッチング時間13ns以下での波長選択動作に成功した。
The PLZT-based monolithic tunable wavelength filter with multiple channel phase shifters was designed and fabricated. Crosstalks of the filter were -14 dB for TE polarized light and -13 dB for TM polarized light, respectively. The filter 3-dB bandwidth and the response time were 110 GHz and less than 40 ns for both polarizations. The operation method of the spectrum control circuit was studied. The variable bandwidth filtering and arbitrary delay operation were successfully demonstrated with the spectrum control circuit. The silica-based arrayed-waveguide gratings and the PLZT-based optical switches were hybrid integrated and it showed the fast wavelength selective operation with a switching time of less than 13 ns.
