Study of the highly dispersive dual-core photonic crystal fiber with large mode area

摘要

The very high dispersive dual-core photonic crystal fiber is analyzed by the full-vector finite element method. The dependence of the phase-matching wavelength (PMW) and the full width at half-maximum (FWHM) on the refractive index of the doped inner core, the diameter of air holes and the hole pitch is demonstrated. The dispersion value is as large as -1427 ps/(nm km) and the effective mode area of the fundamental mode, 82.06 um~2 are obtained.
