Outline of Research at the Start

画像計測の分野で用いられている位相再構成手法を高速時系列直接検波光信号の位相読み取りに適用する。これにより、直接検波だけを用いて光信号の位相を検出することができる新しい種類の光ファイバ通信方式の実現を目指す。具体的な手法として、1次元分散媒質中を伝搬する光波に関する強度輸送方程式を解くことによって、受信機内の分散性ファイバを伝送させる前と後の強度波形から受信信号の位相を算出する方式を採用する。誤差が少ない位相再構成が可能であるための信号の条件を理論的に明らかにすると同時に、実験による検証を行う。

Outline of Final Research Achievements

Complex field reconstruction from direct-detection intensity waveforms of optical signals realizes simple and low-cost yet high-speed data transmission suitable for short-reach ( < hundred kilometers ) systems such as those used in inter-data-center networks. This research studies effectiveness of various algorithms for complex field reconstruction in direct detection optical receivers. Issues such as applicabilities of the algorithms to different modulation formats and tolerance to noise are discussed.

Academic Significance and Societal Importance of the Research Achievements

光信号の直接検波においては受信信号の位相情報が基本として失われる。検波によって消失した位相情報を強度情報からどのようにして/どれだけ忠実に/どれだけ制約なく回復できるかを明らかにすることは、光ファイバ通信への応用に限らず工学や科学の幅広い分野における重要な課題である。光ファイバ通信において、直接検波によって取得した強度情報から受信光信号の位相を読み出すことによって、簡素な受信機構成による低コストで安定性のよいデータ伝送システムを構築でき、社会の情報通信基盤の発展に貢献できる。
