Analysis of mode coupling in the dispersion compensating photonic crystal fiber

The mode coupling in the dispersion compensating dual-core photonic crystal fiber is numerically investigated by the full-vector finite element method (FEM) with transparent boundary condition (TBC). The dependence of the phase-matching wavelength, the confinement loss, the effective mode area and the dispersion on the refractive index of the doped inner core, the diameter of air holes and the pitch is demonstrated. The dispersion value as large as -1426 ps/(nm -km), the effective mode area, 80 μm2 and confinement loss, 1.86×10-6 dB/m at λ=1.55μm are obtained.
