    • By optimizing the refractive index profile, the absorption coefficient of a rare earth element doped optical fiber can be enlarged and nonlinear effect can be suppressed. Thus, according to the present invention, the optical fiber, which is suitable for wide band optical amplification, can be realized. Moreover, in the present invention, the optical fiber of W-shape profile comprising a core, the first cladding having a refractive index smaller than that of said core surrounding said core, and the second cladding having a refractive index smaller than that of said core and larger than that of said first cladding surrounding said first cladding is prepared and are suitable for the wide band optical amplification. That is, since in the rare earth element optical fiber of this W-shape profile, both the absorption coefficient of a rare earth element, and the absolute value of chromatic dispersion can be increased greatly as compared to the optical fiber of the conventional step index profile and nonlinear effect can be suppressed more efficiently, an optical fiber which is suitable for further wide band optical amplification, is realizable.
    • 通过优化折射率分布,可以扩大稀土元素掺杂光纤的吸收系数,并且可以抑制非线性效应。 因此,根据本发明,可以实现适用于宽带光放大的光纤。 此外,在本发明中,包括芯的W型轮廓的光纤,所述第一包层的折射率小于围绕所述纤芯的所述纤芯的折射率,所述第二包层的折射率小于所述芯的折射率 并且比围绕所述第一包层的所述第一包层的尺寸大,并且适合于宽带光学放大。 也就是说,由于在这种W形轮廓的稀土元素光纤中,稀土元素的吸收系数和色散的绝对值都可以与传统步长的光纤相比大大增加 可以更有效地抑制轮廓和非线性效应,适用于进一步的宽带光放大的光纤是可实现的。
