Title (EN) SPOT SIZE CONVERTER AND MANUFACTURING METHOD THEREFOR
(FR) CONVERTISSEUR DE TAILLE DE POINT ET SON PROCÉDÉ DE FABRICATION
(JA) スポットサイズ変換器、及びその製造方法
Abstract:
(EN) The present invention provides a spot size converter that couples optical waveguides of different sizes with high efficiency and low loss, and has high axial misalignment resistance and design flexibility. A spot size converter coverts a beam diameter between optical wires of different core sizes, and comprises: a first surface optically connected to a first optical wire of a first size; a second surface optically connected to a second optical wire of a second size larger than the first size; and a tapered polymer waveguide the diameter of which conically decreases from the first surface toward the second surface.
(FR) La présente invention concerne un convertisseur de taille de point couplant des guides d'ondes optiques de différentes tailles avec un rendement élevé et une faible perte, et ayant une résistance au désalignement axial et une flexibilité de conception élevées. Un convertisseur de taille de point couvre un diamètre de faisceau entre des fils optiques de différentes tailles de noyau, et comprend : une première surface connectée optiquement à un premier fil optique d'une première taille ; une seconde surface connectée optiquement à un second fil optique d'une seconde taille plus grande que la première dimension ; et un guide d'onde polymère effilé dont le diamètre diminue de façon conique à partir de la première surface vers la seconde surface.
(JA) サイズの異なる光導波路同士を高効率、低損失で結合し、かつ高い軸ずれ耐性と設計自由度を有するスポットサイズ変換器を提供する。異なるコアサイズの光配線間でビーム径を変換するスポットサイズ変換器において、第1のサイズの第1光配線に光学的に接続される第1の面と、前記第1のサイズより大きい第2のサイズの第2光配線に光学的に接続される第2の面と、前記第1の面から前記第2の面に向かって円錐状に径が小さくなるテーパ型のポリマー導波路と、を有する。
