Analysis and optimization of an optical frequency comb for multiple channel transmission in a fiberoptic system

The proposed scheme was successful in generating equally spaced frequency combs by launching three continuous-wave pumps at 1 nm wavelength with 10 MHz linewidth using FWM in multiple highly non-linear fibers. Variations in pump power and frequency separations were explored to determine the effect of the input parameters on the frequency comb generation. The dispersion effect and EDFA length are shown to have a significant effect on the comb width as well. Results show that for an optimized number of pumps, the scheme is successful in generating the spectral lines for a specific bandwidth.
