| 摘 要： | 对光子晶体光纤包层3个空气孔之间节区的传光特性进行了分析, 对比了纤芯与包层节区传光的模场面积、非线性系数及色散特性, 得到光子晶体光纤包层节区具有小芯、高非线性的特点.在包层空气孔较大的情况下, 得到了双零色散曲线.根据色散曲线, 分析了色散波产生的相位匹配特性, 得到了色散波中心波长随抽运波长及功率的变化规律.制备出了所设计的光子晶体光纤, 实验得到了在可见光及红外大于300 nm的宽带色散波, 并给出了色散波随抽运波长及功率的变化规律.实验和理论分析结果一致, 为波长变换及超连续宽带光源的研究奠定了基础.

| Abstract: | The optical properties of photonic crystal fiber cladding knot among the three air holes are analyzed. The mode area, nonlinear coefficient and dispersion characteristics of the core and cladding knot are contrasted. Cladding knot of photonic crystal fiber has a small core and highly nonlinear characteristics. For larger cladding air holes, double zero dispersion curves are obtained. According to the dispersion curve, phase-matching features are analyzed for dispersive wave generation. Variation rules of the central wavelength of the dispersive wave with pump power and wavelength are achieved. The photonic crystal fiber designed is fabricated. The visible and infrared broadband dispersive waves above 300 nm are obtained in experiment. Experimental and theoretical results are completely consistent with each other. These are foundation for wavelength conversion and supercontinuum broadband light source. |
