In this presentation we would discuss design and fabrication issues with regard to dispersion tailoring of optical fibers for specialty applications. Various design tools, which could be exploited for such purpose, would be discussed.

We report design and subsequent fabrication of an intrinsically gain flattened Erbium doped fiber amplifier (EDFA) based on a highly asymmetrical and concentric dual-core fiber, inner core of which was only partially doped. Phase-resonant optical coupling between the two cores was so tailored through optimization of its refractive index profile...
