摘要

本发明涉及一种改进了工作特性的掺铒光纤放大器。决定掺铒光纤放大器工作特性的参数为光纤芯内铒的浓度;掺铒光纤芯半径与光纤芯半径之比，以及光纤长度之比。现在已经认识到，通过改变光纤的芯包层折射率差可以提高光纤放大器的性能。这里定义了各种参数，以提供具有最佳增益特性的掺铒光纤放大器。

Erbium-doped Fiber Amplifier

This invention relates to an Erbium doped fiber amplifier having improved operating characteristics. Parameters which determine the operating characteristics of an erbium doped fiber amplifier are the concentration of erbium in the core of a fiber; the ratio of the radius of the core of the fiber doped with erbium relative to the radius of the core of the fiber, and, the length of the fiber. It is now recognized that improved fiber amplifier performance can be obtained by varying the core-cladding refractive index difference of the fiber. The various parameters are here defined for providing an erbium doped fiber amplifier having optimum gain characteristics.
