Spectral widening by using the cross-phase modulation in a linearly birefringent optical fiber is investigated numerically. The coupled nonlinear Schroedinger equation that describes the wave propagation of each polarization in a birefringent optical fiber is discussed. Based on this equation, we generated computer simulations for different values of birefringence and dispersion. We found that a smooth output signal with intensity fluctuations of less than 10% and a spectral width of more than 50 {Angstrom} is possible with low dispersion and low birefringence, e.g., D = {minus}10 psec/nm-km and {delta}n 2 {times} 10{sup {minus}5}. We also found that the Raman effect does not play an significant role.
