Abstract

We numerically and experimentally demonstrate an all fiber parametric frequency combs generator with only one continuous-wave (CW) laser. The light from the laser is launched into a section of fiber to stimulate Brillouin scattering. The scattered Stokes wave and the transmitted wave are used as two seeds to pump parametric process in a highly nonlinear fiber (HNLF). The generated comb lines with a spacing equal to a Brillouin frequency shift of the fiber. To further improve the experimental results, the length of single mode fiber (SMF) used for pulse compression is optimized by numerical simulation. The results show that with a 100-m SMF, a 38-tone frequency comb spaced at 10.67GHz with a 10dB power variation can be obtained.
