用简单的分段模型分析了内插特殊光学元件的掺镱光纤放大器 ,分析表明 ,隔离器、滤波器和光纤光栅的使用不但可以提高放大器增益 ,而且同时能够使噪声特性得到优化 ,文中还讨论了隔离器、滤波器在光纤内的最佳位置。
The analysis of the ytterbium-doped fiber amplifier with special optical elements by simple piecewise model shows that the use of isolators, filters and fiber gratings can not only improve the gain of the amplifier, but also optimize the noise characteristics. The paper also discusses The isolator, the best filter in the fiber.
