Optical communication link dispersion limits the data transfer rate and must be compensated in long haul communication systems. One way to realize the task is to use dispersion compensating fiber, which can be designed to have large negative dispersion. A short length of fiber having high negative dispersion can efficiently compensate the accumulated dispersion in an optical fiber link. Here we propose design of dual core segmented cladding dispersion compensating fiber with very large effective area. We have numerically simulated the design for narrow band dispersion compensation. Fiber design consists of two concentric cores with outer cladding as segmented cladding. By choosing suitable design parameters, resonance takes place between the two cores which helps in increasing the mode area of the fiber. Segmented cladding of the fiber which is highly asymmetric helps in maintaining high negative dispersion. We have used transfer matrix method in conjunction with radial effective index method for modal analysis of the fiber. Wavelength bandwidth of the fiber having high negative dispersion can be easily controlled by various design parameters. Magnitude of the dispersion can be controlled by separation between the two cores. The maximum negative dispersion which we have achieved is -7632 ps/km/nm at 1532 nm wavelength with very high effective area of 127.44 μm 2 . The designed fiber should be a good candidate for compensating the dispersion in an optical communication link.
