In this paper, we analyze the influence of positive and negative third order dispersion (TOD) on soliton interaction. The peculiar nature of soliton as massive particle results in interaction of in-phase soliton, which has resulted in perfect collision in 160[Formula: see text]Gbps system at the interaction point, [Formula: see text][Formula: see text]Km within one collision period of [Formula: see text][Formula: see text]Km. The TOD normally helps in soliton shift from its initial position. We demonstrate how this shifting of TOD helps in preventing the interaction at 2202.6[Formula: see text]Km with an initial relative spacing and pulse width of in-phase soliton [Formula: see text] and 1.77[Formula: see text]ps, respectively. As the TOD has its influence near zero dispersion point of fiber, we choose the dispersion parameter of fiber as [Formula: see text][Formula: see text]ps2/Km. On considering the positive and negative TOD, the interaction was prevented at [Formula: see text], which is characterized in terms of Q-value in a single channel telecommunication system. It is seen that for positive TOD with the values of [Formula: see text] and 0.07[Formula: see text]ps3/Km, the system yielded the Q-value of 88.33 and 54.81, respectively, while for negative TOD with the values of [Formula: see text] and [Formula: see text][Formula: see text]ps3/Km, the Q was 84.47 and 38.25, respectively.

AbstractIn this work, a dispersion compensating photonic crystal fiber (DC-PCF) is proposed in which dispersion, dispersion slope, second order dispersion, third order dispersion, nonlinearity, effective mode area, V parameter are investigated. The suggested structure is very effective for compensating of chromatic dispersion about −951 to −3075.10 ps/(nm.km) over 1340–1640 nm wavelength bandwidth. With perfectly matched layer boundary condition, guiding properties are inspected applying finite element method (FEM). The investigated results conform the opportunity of large negative dispersion and high group velocity dispersion (GVD) of −2367.10 ps/(nm.km) and 3018.55 ps2/km respectively, at 1550 nm operating wavelength. The offered fiber also shows low third order dispersion about −637.88 ps3/km, high nonlinearity of 91.11 W−1 km−1. From overall simulation results, it can be expected that the suggested PCF will be an effective candidate in high bit rate long haul optical communication system as well as sensing applications.
