摘要： Fluoride glass-based optical fiber for an optical amplifier which contains rare earth metal ions in the core glass. The fluoride glass core is doped with rare earth metal ions, and part of the fluorine in the fluoride glass is substituted by at least one halogen. Pr 3+ , Pr 3+ -Yb 3+ -Nd 3+ , or Pr 3+ -Er 3+ can be doped as the rare earth metal ions. Chlorine, bromine or iodine may be used as the halogen.

摘要： An optical amplifier having a tellurite glass as an optical amplification medium, characterised by comprising:
a dispersion medium which is placed on at least one position in the front of or at the back of the optical amplification medium, wherein
the dispersion medium compensates for dispersion of wavelengths by a value of chromatic dispersion that takes a plus or negative number opposite to a value of chromatic dispersion for the optical amplification medium. In the figure, an optical signal enters from the left and exits from the right of the optical amplifier. Input signal light passes through optical isolator 201a and then, combined with excitation light from excitation light source 202, through optical coupler 203. Then the combined signal light passes into optical fiber 205 for optical amplification after passing through a dispersion medium 204. Signal light amplified by optical fiber 205 is then outputted through optical isolator 201b.摘要翻译： 一种具有碲化物玻璃作为光学放大介质的光放大器，其特征在于，包括：分散介质，其被放置在所述光放大介质的前面或后面的至少一个位置，其中所述分散介质补偿 波长乘以与光放大介质的色散值相反的正数或负数的色散值。 在该图中，光信号从左侧入射并从光放大器的右侧离开。 输入信号光通过光隔离器201a，然后与来自激发光源202的激发光通过光耦合器203组合。然后，组合信号光通过光纤205，用于在通过分散介质204之后进行光放大。信号光放大 然后通过光纤205输出光隔离器201b。
