A NOVEL DESIGN OF A DISPERSION COMPENSATING FIBER

We propose a novel dispersion compensating fiber design consisting of two highly asymmetric concentric cores. We show that the fundamental m ode of the proposed fiber can have very large negative dispersion valu es [similar to-5100 ps/(nm.km)] with larger mode field diameter (simil ar to 8-9 mu m) relative to the existing dispersion compensating fiber s.
