In this paper, we report the numerical analysis of a photonic crystal fiber (PCF) for generating an efficient supercontinuum medium. For our computational studies, the core of the proposed structure is made up of As2Se3 and the cladding structure consists of an inner ring of holes made up As2Se3 and four outer rings of air holes in MgF2. The proposed structure provides excellent nonlinear coefficient and dispersion optimization. For the analysis, finite difference frequency domain (FDFD) method is employed. Because of the high nonlinear refractive index of the chalcogenide glass and high difference between the refractive index of the core and the cladding, a small effective mode area of 0.68 μm 2 is obtained. The nonlinear coefficient is 14.98 W -1 m -1 at the wavelength of 1.8 μm. Dispersion is almost flat from 1.6 μm up to 2.8 μm.The supercontinuum spectrum calculated ranges from 1 μm to 6 μm. The presented structure is appropriate for medical imaging, optical coherence tomography and optical communications.

“…The mode coupling between the inner core and the outer core ring causes a negative dispersion in the fiber. The second core can be created in the fiber in many ways, like reducing the diameters of the air holes in one of the rings [8], [9] or using another material in a ring [10], [11] or removing one ring of the air holes [12], that all ends in an increase in the refractive index in the ring.…”

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 elliptical holes in the first ring of the inner core clad of a dispersion compensating fiber of the hexagonal lattice, increases the wavelength range of the dispersion compensation, and causes this fiber to have the capability of dispersion compensation in the whole E to U telecommunication bands. In this fiber, the minimal dispersion will be -1006 ps/(nm.km) at the 1.68 μm wavelength and at the 1.55 μm wavelength the dispersion coefficient will be -710 ps/(nm.km). The simulations are all done using the finite difference time domain numerical method.

“…Investigation shows that high birefringence exhibits well performance in the performance optimization of fiber-optic communication systems, and will also find application in the fabrication polarization maintaining fiber [4][5]. Dispersion will be used in the investigation of dispersion compensation fiber and improve the transmitting quality by reducing attenuation and broadening of signal [6][7][8][9][10].…”
