Paper Abstract

We demonstrate a stable coherent dual comb generator with two phase/intensity-modulated combs. The optical fiber path induced phase fluctuation results in the coherent dual comb beating phase noise. We transfer this phase noise to a 40MHz intermediate frequency with dual-heterodyne phase error transfer, decreasing by a phase-locked loop and optical phase locked loop. Under the scheme, stable coherent dual comb with slightly different repetition rates and offset frequency is generated.
