中文摘要：
与传统光纤不同，光子晶体光纤可以具有多个零色散波长，在四波混频光谱中，具有更丰富的相位匹配特性。目前很多文献报道了光子晶体光纤非线性光学特性的实验结果，但对其产生机理及光谱的变化规律缺乏详细的理论分析。为此对光纤中四波混频原理进行了分析，给出了高增益的相位匹配条件。利用多极法计算了光子晶体光纤的非线性系数及色散特性。对具有多个零色散波长光子晶体光纤的相位失配特性进行了分析，得到了相位匹配波长随泵浦波长及泵浦功率的变化规律。给出了相位匹配曲线，分析了不同色散曲线的相位匹配波长特点，两个零色散波长光子晶体光纤，在四波混频光谱中将激发出四个新的波长。实验得到了两个零色散波长光子晶体光纤的四波混频光谱，与理论分析一致，验证了相位匹配理论的可靠性。多个零色散波长光纤，能产生丰富的相位匹配曲线，会出现更多的四波混频波长，可以有效的控制光孤子及超短脉冲的四波混频及共振散射产生的光谱特性。为光子晶体光纤中基于四波混频的波长变换及超连续谱的研究提供了理论指导。
英文摘要：
In the present paper,the four-wave mixing principle of fiber was analyzed,and the high-gain phase-matching condi-tions were shown.The nonlinear coefficient and dispersion characteristics of photonic crystal fibers were calculated by multipole method.The phase mismatch characteristics of fibers with multiple zero-dispersion wavelengths were analyzed for the first time. The changing rules of phase matching wavelength with the pump wavelength and the pump power were obtained,and the phase matching curves were shown.The characteristics of phase matching wavelengths for different dispersion curves were analyzed. There are four new excitation wavelengths of four-wave mixing spectrum in two zero-dispersion wavelength photonic crystal fi-bers.Four-wave mixing spectroscopy of photonic crystal fibers with two zero-dispersion wavelengths was obtained in the experi-ment,which is consistent with the theoretical analysis,and verified the reliability of the phase matching theory.The fiber with multiple zero-dispersion wavelengths can create a rich phase-matching topology,excite more four-wave mixing wavelengths,ena-bling enhanced control over the spectral locations of the four-wave mixing and resonant-radiation bands emitted by solitons and short pulses.These provide theoretical guidance for photonic crystal fiber wavelength conversion and supercontinuum generation based on four-wave mixing.
