Abstract

La présente invention concerne un appareil optique (110, 500, 600, 800, 1000) permettant d'obtenir une lumière possédant une polarisation linéaire sélectionnée avec un rapport de polarisation. Cet appareil (110, 500, 600, 800, 1000) comprend une terre rare fournissant une lumière possédant une première longueur sensible à une lumière pompée de réception qui possède une seconde longueur d'onde différente de la première longueur d'onde. Si la longueur de la fibre optique (120, 504, 604, 804, 1004) est placée dans une première position entre la longueur de la fibre (120, 504, 604, 804, 1004) sensiblement linéairement orientée (20), cette fibre (120, 504, 604, 804, 1004) peut propager à la première longueur d'onde un mode fondamental et une pluralité de modes d'ordre supérieur et, cet appareil (110, 500, 600, 800, 1000) peut fournir une lumière possédant dans un premier rapport de polarisation pour la polarisation linéaire sélectionnée et un paramètre M2 et, si la longueur de fibre (120, 504, 604, 804, 1004) est placée dans une seconde position qui augmente la perte par courbure de la fibre par rapport à la première position de sorte que, sensible à cette perte par courbure augmentée, cet appareil (110, 500, 600, 800, 1000) puissent fournir une lumière possédant un paramètre M2 réduit ainsi qu'un second rapport de polarisation pour la polarisation sélectionnée qui est augmentée par rapport au premier rapport de polarisation, cette augmentation étant au moins de 6 dB supérieure au premier rapport de polarisation et, lorsque la longueur de la fibre (120, 504, 604, 804, 1004) est dans la seconde position, l'appareil (110, 500, 600, 800, 1000) peut fournir une efficacité de pente qui est au moins de 50 % du rapport seconde longueur d'onde sur première longueur d'onde.
