A highly dispersive dual core quasi-periodic photonic crystal fiber is proposed for chromatic dispersion compensation. The dispersion for the dual concentric core fiber is optimized to compensate the chromatic dispersion with a high negative dispersion, accomplishing the communication bandwidth from S-band (1460 nm) to L-band (1625 nm). By precise control of structural parameter we have achieved a maximum dispersion of −18,838 ps/nm-km with the phase matching wavelength centred around 1.55μm. We also numerically investigate the influence of structural parameter and doping effects and its response on peak dispersion parameter.

Fivefold Symmetric Photonic Quasi-Crystal Fiber for Dispersion Compensation from S- to L-Band and Optimized at 1.55 μm

Advances in OptoElectronics

Dispersion causes optical pulses broadening and must be compensated for in long-distance high-speed optical data transmission systems. We investigate optical properties of micro structured fiber with 5-fold symmetric quasicrystal lattice of air-holes in a silica matrix for the first time. Dual-Concentric core Photonic Quasicrystal Fiber (DC-PQF) lattices with varying hole diameters were investigated and curves for the effective index, dispersion parameter and confinement losses were calculated by finite element method. For dispersion compensation purpose, we have proposed a novel 5-fold PQF with a high negative dispersion values â 16,000 ps/(nm-km) could be reached for the wavelength around 1310 nm.
