基于光子晶体光纤光脉冲压缩的理论研究

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。

Theoretic research on optical pulse compression by using photonic crystal fiber

The optical pulse compression by using a photonic crystal fiber with high nonlinear coefficient is discussed theoretically.The high quality optical pulses compression can be obtained by a fiber of shorter length.According to the limitation of such method for pulse compression,a novel method by using nonlinear optical loop mirror based on crystal fiber for pulse compression is proposed.The theoretical results show that the optical pulse with low peak power itself can be compressed by using such method.Compar...
