我们理论上并且试验性地显示出在信号之间的比率的影响并且更闲散在连续波浪(CW ) 在获得特征上从 PIA 部分产生了抽非退化的串联阶段敏感的纤维光参量的放大器(PS-FOPA ) 。结果证明使用产生更闲散的罐头的高度非线性的纤维(HNLF ) 的长度引起力量比率在之间的变化更闲散并且在小信号获得条件下面表明 PS-FOPA 的特征,它显著地影响获得。为了高获得,增加,选择长 HNLF 产生更好更闲散。在我们的实验, 5.5 dB 获得和 18 nm 带宽(开/关获得 > 10 dBm ) 当 300 m 长的 HNLF 在 PIA 被使用而不是 200 m 长的 HNLF 时,在 PS-FOPA,罐头被完成。
We theoretically and experimentally show the impact of the ratio between the signal and idler generated from the PIA part on the gain characteristics in the continuous wave (CW) pump non-degenerate cascaded phase-sensitive fiber optical parametric amplifier (PS-FOPA). The results show that the length of highly nonlinear fiber (HNLF) used for generating the idler can cause the variation of power ratio between the idler and signal, which sign, ificantly affects the gain characteristics of the PS-FOPA under the small signal gain condition. To obtain high gain, it is better to choose long HNLF to generate idler. In our experiment, 5.5 dB gain and 18 nm bandwidth (on/off gain〉 10 dBm) in PS-FOPA can be achieved when 300 m-long HNLF instead of 200 m-long HNLF is used in PIA.
