Abstract

The enhancement of adaptive abilities of nonlinear optical pulses to polarization mode dispersion (PMD) is obtained by modulating breath-depth of two polarization states of the pulses. The breath-depth modulation is realized based on the interaction among self-phase modulation, cross phase modulation, group velocity dispersion and degenerate four-wave mixing, which results in making two polarization states of the pulses into a tighter state when nonlinear pulses propagate in optical fibers with high birefringence. Numerical results show that the transmission stabilities of modulated breath-depth optical pulses are improved in conventional fibers with random birefringence. The pulse broadening trend of the modulated breath-depth pulses induced by PMD is effectively suppressed by our proposed method. The symmetric output pulse shape is also reshaped in conventional fibers.
