Abstract: front page image
(EN)An optical signal transmission system includes: a transmitter which adds an asymmetric chirp to two optical signals having the same frequency so as to phase-modulate the two optical signals, synthesizes the phase-modulated two optical signals as polarization components in polarized multiplexing, and transmits the optical signal obtained by the synthesis; and a receiver which receives the optical signal from the transmitter and executes pulse compression for at least one of the polarization components of the optical signal and separation of the two polarization components from the optical signal.
(FR)L’invention concerne un système de transmission de signal optique comprenant : un émetteur qui ajoute une fluctuation de longueur d’onde asymétrique à deux signaux optiques de même fréquence pour les moduler en phase, effectue la synthèse des deux signaux optiques modulés en phase sous forme de composants de polarisation dans un multiplexage polarisé, et transmet le signal optique obtenu au moyen de la synthèse ; et un récepteur qui reçoit le signal optique provenant de l’émetteur et exécute une compression d’impulsion pour au moins l’un des composants du signal optique et une séparation des deux composants de polarisation du signal optique.
(JA) 光信号伝送システムは、周波数が同一の2つの光信号に非対称なチャープを付加することにより、該2つの光信号を位相変調し、位相変調した該2つの光信号を偏波多重化における偏波成分として合成し、合成により得られた光信号を送信する送信器、及び前記送信器から前記光信号を受信し、該光信号の少なくとも一方の偏波成分に対するパルス圧縮と、該光信号からの2つの偏波成分の分離とを行う受信器、を有する。
