Abstract
光通信システムの超高速化に伴い,光信号のタイミングに課せられる要件はますます厳しくなる.本橋は,面型光スイッチの大面積性及び超高速性を生かし,複数チャンネル一括処理・広ダイナミックレンジ・リアルタイム処理を可能とする超高速光パルスのタイミング計測システム並びにタイミング揺らぎ低減システムのアーキテクチャを示し,有機色素薄膜による面型光スイッチを用いた実証実験を示す.
We show a precision optical pulse timing measurement and control technique using a squarylium dye J-aggregate film, which is an organic molecular film that acts as an ultrafast two-dimensional optical switch. The large area and ultrafast response of the device enables a femtosecond-resolved, large dynamic range, real-time, multichannel timing measurement capability by an architecture where optical pulse timing is directly mapped to space-domain position on the film. A timing fluctuation (jitter, wander, and skew) reduction architecture is also presented and experimentally demonstrated.
