Abstract :
A report is made on the effects of self-phase modulation (SPM) on the group-velocity dispersion measurement technique using the conversion of phase-modulated signal into the amplitude-modulated signals (i.e. PM-AM conversion technique). The results show that the modulation frequency should be in the range 0.3-1 GHz to suppress the SPM-induced errors while maintaining reasonable PM-AM conversion efficiency.
