Abstract: front page image
(EN)An optical circuit device characterized by integrating, on a planar substrate, an optical circuit, a polarized wave separating/combining unit for separating an incoming wave into two polarized waves and combining two polarized waves into an outgoing wave, first and second optical waveguides connecting between the optical circuit and the polarized wave separating/combining unit and receiving the two separated polarized waves individually, and a polarized wave rotating element arranged on the first optical waveguide and rotating the plane of polarization of one polarized wave to become the plane of polarization of the other polarized wave.
(FR)L’invention concerne un dispositif à circuit optique caractérisé par l’intégration, sur un substrat plan, d’un circuit optique, d’un module de séparation/combinaison d’ondes polarisées pour séparer une onde entrante en deux ondes polarisées et combiner deux ondes polarisées en une onde sortante, de premier et deuxième guides d’onde optiques raccordés entre le circuit optique et le module de séparation/combinaison d’ondes polarisées et recevant chacun les deux ondes polarisées séparées, et d’un élément de rotation d’ondes polarisées disposé sur le premier guide d’ondes optique et réalisant la rotation du plan de polarisation d’une onde polarisée pour le faire correspondre au plan de polarisation de l’autre onde polarisée.
(JA) 光回路と、入射波から2つの偏波への分離、及び2つの偏波から出射波への合成を行う偏波分離合成器と、前記光回路及び前記偏波分離合成器の間を接続し、前記分離された2つの偏波が個々に入射される第1及び第2の光導波路と、 前記第1の光導波路に配置され、前記偏波分離合成器により分離された一方の偏波の偏波面を、前記分離されたもう一方の偏波の偏波面となるよう回転する偏波回転素子と、を平面基板上に集積したことを特徴とする光回路装置。
