Abstract

We investigate to generate coherent and frequency-lock optical multi-carriers by using cascaded phase modulators and recirculating frequency shifter (RFS) based on an EDFA loop. 113 coherent and frequency-lock subcarriers with tone-to-noise ratio larger than 26dB are generated. The amplitude difference of subcarriers obtained after a tilt filter covering about 22.6nm is less than 5dB.
