Flexible broadband optical frequency comb generation for dense wavelength-division multiplexing passive optical networks

In this paper, we compare and analyze some schemes of generating the optical frequency comb. We propose a flexible and low-cost broadband optical frequency comb for dense wavelength-division multiplexing passive optical network (DWDM-PON) system by using a CW laser and electro-optic modulators followed by a dispersion flattened high nonlinear fiber (DF-HNLF). The frequency spacing and center wavelength of the frequency comb can be flexibly adjusted by changing the radio-frequency signal and the output wavelength of a continuous-wave (CW) laser, respectively.
