Abstract

We theoretically and experimentally study of the four-wave mixing (FWM) that exists between the co-propagated pump Fabry-Perot (FP) modes of a FP laser diode (FPLD) and the single wavelength probe signal in a 25 km of non-zero dispersion shifted fiber (NZDSF) with zero dispersion wavelength of 1495 nm. The 100-mW co-propagated FP spectra centered at 1440nm are reproduced via FWM around the 1-mW single wavelength signal around 1552 nm. The maximum FWM generated power ratio is found to have the first condition in matching of the group indices of the pump and signal to obtain the maximum FWM efficiency. And the second condition is mapping the signal wavelength to the center wavelength of the FP pump modes to have the adjacent FP modes with larger powers. The zero-dispersion wavelength of NZDSF can also be determined at the middle of the signal and the center wavelength of pump to have the maximum FWM generated power ratio.
