We investigate theoretically the effects of nonlinear phase distortion on synchronization of two identical unidirectionally coupled chaotic semiconductor lasers. When we take into account the self-phase modulation of the transmitted signal in an optical communication channel, we find that distortion severely affects synchronization. The effects of self-phase modulation on synchronization error relative to the power of the transmitting signal and the optical fiber length are studied.
