Abstract
(EN)
Signal light propagating along an optical network is modulated with control light having information relating to the optical network without photoelectric conversion, and a power loss is thereby suppressed. An optical modulator (1) synthesizes the signal light (ES) propagating along the optical network with the control light (ECt) having the information relating to the optical network, and inputs the synthesized signal to a non-liner optical medium. The optical modulator (1) modulates the signal light (ES) with changes in intensity of the control light (ECt) in the non-liner optical medium.
(FR)
Une lumière de signal se propageant le long d'un réseau optique est modulée par une lumière de commande ayant des informations se rapportant au réseau optique sans conversion photoélectrique, et une perte de puissance est par là supprimée. Un modulateur optique (1) synthétise la lumière de signal (ES) se propageant le long du réseau optique avec la lumière de commande (ECt) ayant les informations se rapportant au réseau optique, et met le signal synthétisé en entrée d'un support optique non linéaire. Le modulateur optique (1) module la lumière de signal (ES) avec des changements d'intensité de la lumière de commande (ECt) dans le support optique non linéaire.
(JA)
 光-電気変換することなく光ネットワークを伝搬している信号光を光ネットワークに関する情報を有する制御光によって変調し、電力損失を抑制する。 光変調器(1)は、光ネットワークを伝搬している信号光(ES)に、光ネットワークに関する情報を有する制御光(ECt)を合波して非線形光学媒質に入力する。光変調器(1)は、非線形光学媒質において制御光(ECt)の強度変化により、信号光(ES)を変調する。
