Simplified title:制造用于延伸的L-带(L-BAND)及S-带(S-BAND)放大之硅酸盐波导组合物之方法 A Method for Manufacturing Silicate Waveguide Compositions for Extended L-Band and S-Band Amplification
Abstract in simplified Chinese:根据本发明之制造用于光学放大器中掺杂铒之光学纤维之方法,其包括以下步骤:提供底材管(substrate tube),高纯度、以硅石为主之覆套层系沉积于该管之内部,然后将内核玻璃,其包含硅石、Al、一种非萤光之稀土金属离子、Ge、Er、及Tm,沉积于该管中。该非萤光之稀土金属离子可为La,及该内核可进一步包含F。然后将该管陷缩(collapsed)以形成预成型物。最后,拉伸该预成型物以产生光学纤维。该内核玻璃可为实质上均匀的。该内核可包含至少两个区域,其中一个区域包含与另一个区域实质上不同之Er比Tm比。该等区域可呈环状排列。此种波导之内核可系借由多重MCVD(化学蒸气沉积)信道(passes)、多重溶胶-凝胶信道、或以多重煤灰(soot)沉积、溶液掺杂、及固结(consolidation)信道而制造。
