摘要
设计了一种大纤芯实心Bragg光纤,并从理论上证明,利用这种光纤可以实现大纤芯的双模光纤放大器。纤芯的增大使制作光纤放大器的工艺变得简单,并且可以使泵浦光直接灌入纤芯,这样泵浦光与信号光可以最大限度的重合,从而提高了泵浦光的耦合效率。同时,纤芯的增大使光纤芯区的总能量得以增大,这样就可以得到高功率的光纤放大器。
This paper designs a kind of large solid-core Bragg fibers, which can be used as large solid-core double mode fiber amplifiers, and it can make the manufacture of fibers simplify. Because of the large solid core, the laser can directly pump into fibers, and the pump light can match the signal light. So this design leads to the improvement of coupling effect and the higher power of fiber amplifiers.
