利用高阶模激发光子晶体光纤产生色散波，并测量了色散波波长与偏振态的关系。从理论上计算了不同对称数的各种空间模式的色散特性，确定了四种线偏振高阶模的组合。计算了高阶模色散波的相位匹配条件，发现具有相同空间模的色散波的波长依赖于偏振方向。实验测得的依赖性与理论计算得到的结果吻合得很好。(C)2010年美国光学学会
Dispersive waves were generated from a photonic crystal fiber by higher-order mode excitation and the dependence of their wavelengths on polarization was measured. The dispersion properties of various spatial modes with different symmetry numbers were calculated theoretically and four combinations of linearly-polarizing higher-order modes were identified. The phase-matching conditions of dispersive waves for higher-order modes were calculated and it was found that the wavelengths of dispersive waves with identical spatial modes depended on polarization directions. The dependence measured experimentally agreed well with results obtained by theoretical calculations. (C) 2010 Optical Society of America
