Title (EN) POLARIZATION BEAM SPLITTER
(FR) DIVISEUR DE FAISCEAU DE POLARISATION
(JA) 偏波分離素子
Abstract:
(EN) The purpose of the present invention is to provide a directional coupler type polarization beam splitter having a large allowable range for manufacturing variations. To this end, this directional coupler type polarization beam splitter has: curved waveguides; waveguides that are narrower than the curved waveguides, form optical coupling between facing waveguides and cause polarization separation, and are formed by a waveguide of the same type as the facing waveguide; and tapered waveguides connecting the curved waveguides and the waveguides.
(FR) L'objet de la présente invention est de fournir un diviseur de faisceau de polarisation de type coupleur directionnel ayant une large plage admissible pour des variations de fabrication. À cet effet, l'invention porte sur un diviseur de faisceau de polarisation de type coupleur directionnel qui comprend : des guides d'ondes incurvés; des guides d'ondes qui sont plus étroits que les guides d'ondes incurvés, forment un couplage optique entre des guides d'ondes en regard et provoquent une séparation de polarisation, et qui sont formés par un guide d'ondes du même type que le guide d'ondes faisant face; et des guides d'ondes coniques reliant les guides d'ondes incurvés et les guides d'ondes.
(JA) 本発明の目的は、製造バラつきの許容範囲が大きい方向性結合器型偏波分離素子を提供することである。そのために本発明の方向性結合器型偏波分離素子は、曲げ導波路、前記曲げ導波路よりも細く、対向する導波路との間で光結合して偏波分離を起こし、前記対向する導波路と同タイプの導波路で形成される導波路、前記曲げ導波路と前記導波路の間をつなぐテーパ導波路、を有する。
