An internal structure of an arrayed-waveguide module is changed. Monitor optical signals necessary for a wavelength multiplexer transmission signal are extracted by an arrayed-waveguide module. The size of an optical circuit can be decreased. The structure of the resultant apparatus can be simplified. The number of fabrication steps of the apparatus can be decreased.

La structure intérieure d'un module de guides d'ondes en réseau est modifiée. Des signaux optiques de contrôle nécessaires pour un signal de transmission multiplexé en longueur d'onde sont extraits au moyen d'un module de guide d'ondes en réseau. Ainsi, la longueur du circuit optique peut être réduite, la structure de l'appareil résultant peut être simplifiée, et le nombre d'étapes dans la fabrication de l'appareil peut être diminué.
