| چکیده | ||
| In this paper, a new structure is provided for the dispersion compensating photonic crystal fibers in order to broaden the chromatic dispersion and increase the dispersion compensating capability in a wide wavelength range. In the structure, putting a combination of circular holes and a star structure in the inner core clad causes the dispersion coefficient profile to be broadened, and additionally causes the fiber to have a negative dispersion coefficient in the whole S to U telecommunication bands. In this fiber, the minimal dispersion coefficient will be -653ps/(nm.km). Furthermore, with the diameter of the circular holes of the inner clad in this structure increased, a relatively flat dispersion profile will be obtained in the whole E to U telecommunication bands with a dispersion variation equal to 46ps/(nm.km). In the S to C telecommunication bands, the dispersion variation is 17ps/(nm.km). The simulations are all done using the finite difference time domain numerical (FDTD) method. | ||
