Title (EN) LIGHT AMPLIFIER AND METHOD FOR MANUFACTURING THE SAME
(FR) AMPLIFICATEUR DE LUMIÈRE ET SON PROCÉDÉ DE FABRICATION
(JA) 光増幅器及びその製造方法
Abstract: front page image
(EN)Disclosed is a small-sized, highly efficient light amplifier having a PLZT optical waveguide layer to which a rare earth element is added. Also disclosed is a method for manufacturing such a light amplifier. Specifically disclosed is a light amplifier characterized by having an optical waveguide layer which contains Pb1-xLax(ZryTi1-y)1-x/4O3 (PLZT: 0 < x < 0.3, 0 < y < 1.0). This light amplifier is further characterized in that the optical waveguide layer is composed of a single crystal film which is formed by epitaxial growth and doped with Yb (ytterbium) in an amount of not less than 0.2% by mole but not more than 11.0% by mole.
(FR)L'invention concerne un amplificateur de lumière de petite taille, à haut rendement, ayant une couche de guide d'ondes optique PLZT à laquelle un élément de terres rares est ajouté. L'invention concerne également un procédé de fabrication d'un tel amplificateur de lumière. L'invention concerne de façon spécifique un amplificateur de lumière, caractérisé par le fait qu'il a une couche de guide d'ondes optique qui contient Pb1-xLax(ZryTi1-y)1-x/4O3 (PLZT : 0
(JA) 希土類元素を添加したPLZT光導波路層を有する光増幅器であって、小型で高効率な光増幅器及びその製造方法を提供すること。  Pb1-xLa(ZrTi1-y1-x/4(PLZT:0<x<0.3、0<y<1.0)を含んで構成される光導波路層であって、Yb(イットリビウム)がドープ量0.2モル%以上、11.0モル%以下でドープされ、且つエピタキシャル成長によって形成される単結晶膜からなる光導波路層を有することを特徴とする光増幅器である。
