Abstract:
(EN) Disclosed is an optical amplifier wherein a core, to which a rare earth element is added, is used as an amplification medium of an optical signal, and excitation light for having the rare earth element in the excited state is supplied via a cladding on the outer side of the core. The optical amplifier is provided with coupling means that couple the excitation light with the core mode of the core, said excitation light having been supplied to the cladding and propagated in the cladding in cladding mode. The plurality of coupling means are provided in the long axis direction of the optical amplifier.
(FR) L'invention concerne un amplificateur optique dans lequel un cœur, auquel un métal des terres rares est ajouté, est utilisé comme moyen d'amplification d'un signal optique, et la lumière d'excitation est fournie par l'intermédiaire d'une gaine sur le côté extérieur du cœur, de manière à faire passer le métal des terres rares à l'état excité. L'amplificateur optique est pourvu de moyens de couplage qui couplent la lumière d'excitation au mode lié du cœur, ladite lumière d'excitation ayant été fournie à la gaine et propagée dans cette dernière en mode de gaine. La pluralité de moyens de couplage sont disposés dans le sens de l'axe long de l'amplificateur optique.
(JA) 希土類元素が添加されたコアを光信号の増幅媒体とし、前記希土類元素を励起状態にするための励起光が前記コアの外側のクラッドを経由して供給される光増幅器は、前記クラッドに供給されクラッドモードで該クラッド内を伝搬している励起光を前記コアのコアモードに結合させる結合手段を備え、前記結合手段は、前記光増幅器の長軸方向において複数設けられる。
