Abstract

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.
