摘要:

提出和设计了一种宽带宽、高增益和增益平坦的光纤参量放大器,它具有双泵浦和两段高非线性光纤级联的结构。选择光纤的四阶色散系数作为优化的指标之一,用普通的数组循环计算法,对双泵浦及两根高非线性光纤组成的系统进行模拟,获得了峰值增益62.46dB,起伏小于5dB,带宽高达424nm的光纤参量放大器。

Abstract:

Two-pump fiber optical parametric amplifier (FOPA) with two-section highly nonlinear fibers is proposed and demonstrated, which has broad bandwidth, high and flat gain. Using the fourth-order dispersion coefficient of the fibers as a pivotal factor, the optimization of the gain characteristics of the FOPA with double pumps and two section fibers has been achieved. The results show that present FOPA has 424nm bandwidth with 62.46dB average gain and gain ripple less than 5dB.

Key words: fiber and waveguide optics fiber, optical parametric amplifier, two-pump, cascaded two-section fiber
