Dispersion Slope Compensating Photonic Quasicrystal Fiber over S+C+L Band
For multichannel dispersion compensation in dense wavelength division multiplexing (DWDM) systems optical communication networks, a broadband dispersion slope compensating photonic quasicrystal fiber (PQF) is proposed. The PQF has a sixfold symmetric quasiperiodic array of air holes in cladding and a high index rob in the concentric core. The simulating results of the dispersion slope and dispersion of PQF reveal that the relative dispersion slope (RDS) can reach a low value 0.004 4 nm-1 to 0.002 9 nm-1 that is equal to the standard single mode fiber (SMF) over S+C+L band approximately; the PQF can achieve dispersion slope compensation effectively, while obtain a larger negative dispersion coefficient of -2 476 ps·nm-1·km-1 over optical communication band 1 460 nm to 1 625 nm. The value of dispersion compensation result is (-0.5~0)ps·nm-1·km-1 to the SMF in the S+C+L band. The designed PQF can achieve multichannel dispersion compensation, simplify the structure and reduce compensation costs, and then it can be used for wideband dispersion slope compensation.
