%X Cross-phase modulational instability created by two beams of lights in the region of minimum group-velocity dispersion is investiga ted based on extended nonlinear Schrdinger equation with the fiber loss and high -order dispersion considered.The dispersion equation which describes the cross -phase modulational instability is obtained,and the numerical simulation is don e.It is shown that because of the fourth-order dispersion,cross-phase modulati onal instability occurs at two spectrum regions in both anomalous and normal dis persion regimes of fiber. When second-order dispersion approaches the minimum v alue at the so-called zero dispersion wavelength,fourth-order dispersion domin ates the cross-phase modulational instability and makes a new crest in the gain spectrum.Research also shows that fiber loss reduces the frequency range of the gain spectrum.For a given dispreading distance,the widths of the two spectrum r egions increase until overlay when second-order dispersion approaches zero.When two beams of lights have difference,the cross-phase modulational instability i s analyzed numerically.
