Abstract This paper proposed an approach to design an evenly spaced, 1.8 THz spectrally broad and 1.6 dB flat optical frequency comb (OFC) by exploiting the cross-phase modulation in highly nonlinear fiber. The OFC is realized by controlling the phase of the signals in two parallelly placed highly nonlinear fibers. The frequency and line spacing of the OFC can be tuned by simply varying the periodicity and central wavelength of input electrical and optical signal, respectively.

A wideband optical frequency comb (OFC) generator using a fiber re-circulating loop (FRL) including a phase modulator and optical amplifier, cascaded with a spectrum expander containing a high-power erbium-doped fiber amplifier and highly nonlinear fiber (HNLF) is proposed and experimentally demonstrated, in which the FRL is used as a source to generate seed comb lines, and then generated seed comb lines are extended to a wideband optical frequency comb using cascaded four-wave mixing in the HNLF. Only using one stage spectrum expander, a stable 20-GHz optical comb with 201 comb lines within 30-dB power deviation, spanning 40-nm bandwidth, is achieved. The results show that the HNLF has unique ability to broaden output spectrum from the FRL. In addition, an optical frequency comb is dramatically broadened, which may be predicted by optimizing gain and dispersion of the FRL or configuration of the spectrum expander, or both.
