Propagation of solitons in singlemode birefringent fibers is considered under the presence of thirdorder dispersion (TOD). The behavior of two neighboring solitons and their interaction is investigated under the presence of thirdorder dispersion with different group velocity dispersion (GVD) parameters. It is found that thirdorder dispersion makes the resultant soliton to deviate from its ideal position and increases the interaction between adjacent soliton pulses. It is also observed that this deviation due to thirdorder dispersion is considerably small when the optical pulse propagates at wavelengths relatively far from the zerodispersion. Modified coupled nonlinear Schrödingers equations (CNLSE) representing the propagation of optical pulse in single mode fiber with TOD are solved using splitstep Fourier algorithm. The results presented in this paper reveal that the thirdorder dispersion can substantially increase the interaction between the solitons, but large group velocity dispersion reduces the interaction between neighboring solitons.
