A superfluorescent fiber source outputs highly polarized light without a substantial decrease in output power efficiency. According to one embodiment, a polarizer is spliced within the superfluorescent fiber at a selected location along the length of the fiber (e.g., near the middle of the fiber). According to another embodiment, the entire length of the superfluorescent fiber is polarizing to thereby assure that one of the polarizations of light is substantially extinguished while the other polarization of light is nearly double the power which that polarization would have if the polarizer were not present within the superfluorescent fiber. In this manner, superfluorescent sources can be adapted especially for use in fiber optic gyroscopes, or the like, which require highly polarized light, without a substantial reduction in efficiency.

Source à fibre superfluorescente produisant une lumière hautement polarisée sans diminution sensible d'efficacité de la puissance de sortie. Suivant une version, un polariseur est raccordé à l'intérieur de la fibre superfluorescente à un certain endroit sur sa longueur (p. ex. près du milieu). Suivant une autre version, la fibre superfluorescente est polarisante sur toute sa longueur de telle sorte qu'une des polarisations de lumière est pratiquement coupée tandis que l'autre polarisation de lumière a près de deux fois plus de puissance que si le polariseur n'était pas présent dans la fibre superfluorescente. Ainsi, les sources superfluorescentes peuvent être adaptées pour des gyroscopes à fibres optiques, ou des dispositifs assimilés, qui nécessitent une lumière hautement polarisée, sans diminution sensible d'efficacité.
