从理论上研究了单根光子晶体光纤的光脉冲压缩,利用较短的具有高非线性系数的光子晶体光纤可以实现较高质量的光脉冲压缩。针对单根光子晶体光纤压缩光脉冲的限制,提出了一种基于光子晶体光纤非线性环路镜中交叉相位调制效应的脉冲压缩方法。理论研究表明,这种脉冲压缩方式可以压缩自身功率较低的信号脉冲,相比于单根光子晶体光纤的方法,可以得到更高压缩质量的脉冲,通过合理选择控制光脉冲的参数,可以有效地抑制基座。
The optical pulse compression of a single photonic crystal fiber is theoretically studied, and higher quality pulse compression can be achieved by using a shorter photonic crystal fiber with high nonlinearity coefficient. Aiming at the limitation of single photonic crystal fiber optical pulse compression, a pulse compression method based on the cross-phase modulation effect in photonic crystal fiber nonlinear loop mirror is proposed. Theoretical studies show that this pulse compression method can compress its own lower power signal pulse, compared to a single photonic crystal fiber method can get higher compression quality of the pulse, by a reasonable choice to control the parameters of light pulse can be effective To suppress the base.
