title: Optimization of dual-core and microstructure fiber geometries for dispersion compensation and large mode area.
abstract: We investigate dual concentric core and microstructure fiber geometries for dispersion compensation. Dispersion values as large as -59 000 ps/(nm km) are achieved, over a broad wavelength range with full width at half maximum exceeding 100 nm. The trade-off between large dispersion and mode area is studied. Geometries with an effective mode area of 30 microm2 and dispersion -19 000 ps/(nm km) and 80 microm2 with -1600 ps/(nm km) are proposed.
