本研究は、実世界とビッグデータなどのデジタル技術をつなぐために必要不可欠なアナログ－デジタル変換システムについて、電子工学的なアプローチの時間ジッタ（信号取得のタイミングの精度）に関するサブピコ秒の限界を超えた超高速信号処理の「未踏の領域」における性能向上の方向性と具体的なアプローチの開拓を目的とし、システム全体の信号高品質化の緻密な分析の結果に基づき、強度ジッタ（信号取得のレベルの精度）に着目した新しい“光化”の取り組みを世界に先駆けて試みる。
本年度は，
①光サンプリング信号の位相・振幅同時評価システムの構築について、時間ジッタおよび強度ジッタに関係する位相および振幅雑音を同時に測定可能なコンスタレーション表示による光サンプリング信号のスクイージングに関する詳細な状態解析を行うため，光サンプリング信号のコヒーレント受信が可能な信号評価システムを構築し、情報通信研究機構と共同して広帯域な短パルスの位相をスペクトル分割して観測することを試みた．
②ショット雑音以下の安定な光ソリトン発生系の構築について、コンスタレーション表示が可能な信号評価システムにより光ソリトン発生系の詳細な状態解析と調整を行う予定であったが，バランスド検出を用いた比較的低繰り返しでの基礎実験によるショット雑音以下でのスクイージング効果の実現を目指し，シミュレーションによる原理確認と実験によるショット雑音レベルでの確認を行った．
③シリコン細線導波路による超安定化の可能性検討については、上記の構築した安定な光ソリトン発生系について，非常に高い非線形光学特性を持つことが報告されているシリコン細線導波路の試作を行い利用可能性の検討を試みた．導波路幅を３種類（0.45, 0.40, 0.35um）、導波路長を３種類（0.95, 1.95, 2.95cm）用意し，入力光パワーを0、10、20dBの３段階で可変減衰させたときの出力光スペクトルを観察し，導波路幅0.45umおよび導波路長1cm以上がスペクトル広がりを起こしやすいことを確認した。
本年度目標としていた①光サンプリング信号の位相・振幅同時評価システムの構築、②ショット雑音以下の安定な光ソリトン発生系の構築、③シリコン細線導波路による超安定化の可能性検討についてそれぞれ、①構築した系での信号評価の動作確認、②シミュレーションによる原理確認と実験によるショット雑音レベルでの確認、③シリコン細線導波路の試作を行い当初の目標を達成したため。各項目の詳細を以下に示す。

First, we developed highly stable optical frequency comb source using nonlinear polarization rotation type ultrashort pulse fiber laser, and octave spanning, coherent supercontinuum comb source. Next, we investigated quasi-dispersion increasing comb profiled fiber. Using the developed comb profile fibers, we demonstrated the narrow linewidth, wavelength tunable comb source. We also developed novel single wall carbon nanotube polyimide film working at 2.0 um wavelength range. Using the developed nanotube film device, an all-fiber type, high power, ultrashort pulse Tm doped fiber laser was developed.
At 1.55 um wavelength range, we demonstrated all-polarization maintaining type, bi-directional dual comb fiber. Then we succeeded in the fundamental experiment of wideband dual comb spectroscopy. Finally, we developed environmentally stable, all-polarization maintaining, figure 9 fiber laser. The dynamics inside the laser and the initial process of passive mode-locking were clarified.
