Abstract: The present invention provides a method of making rare earth (RE) doped optical fiber using BaO as co-dopant instead of Al or P commonly used for incorporation of the RE in silica glass by MCVD and solution doping technique. The method comprises deposition of particulate layer of GeO2 doped SiO2 with or without small P2O5 for formation of the core and solution doping by soaking the porous soot layer into an aqueous solution of RE and Ba containing salt. This is followed by dehydration and sintering of the soaked deposit, collapsing at a high temperature to produce the preform and drawing of fibers of appropriate dimension. The use of Ba-oxide enables to eliminate unwanted core-clad interface defect which is common in case of Al doped fibers. The fibers also show good RE uniformity, relatively low optical loss in the 0.6-1.6 μm wavelength region and good optical properties suitable for their application in amplifiers, fiber lasers and sensor devices.

Abstract translation: 本发明提供一种使用BaO作为共掺杂剂代替通常用于通过MCVD和溶液掺杂技术将石英玻璃中的RE掺入的Al或P的掺杂稀土（RE）掺杂光纤的方法。 该方法包括沉积具有或不具有小的P 2 O 5的GeO 2掺杂的SiO 2的颗粒层以形成芯并通过将多孔烟灰层浸入含RE和Ba的盐的水溶液中来进行溶液掺杂。 随后将浸渍的沉积物脱水和烧结，在高温下塌陷以制备预制件并拉出适当尺寸的纤维。 使用Ba氧化物能够消除在Al掺杂光纤的情况下常见的不需要的芯包层界面缺陷。 纤维也表现出良好的均匀性，0.6-1.6μm波长区域的光损耗相对较低，适用于放大器，光纤激光器和传感器装置的光学性能良好。
