Summary: | Four wave mixing (FWM) is a nonlinear e�ect observable in optical �bers when light
of two or more wavelengths are launched into the �ber. Parametric ampli�cation is
a consequence of FWM, where depending on the phase di�erence between the waves,
power transfer between the interacting waves could take place. We are interested
in the generation of this phenomenon in optical �bers to create Fiber Optical Para-
metric Ampli�ers (FOPA). In this paper, we simulated the parametric ampli�cation
process in a highly nonlinear �ber (HNLF), focusing on the e�ect of di�erent values
of the initial linear phase mismatch ��, pump power Pp, and nonlinear coe�cient
.
It was found that in terms of the initial �� value, a value closer to zero will result
in a higher maximum signal and idler power. Also, we observed that a larger pump
power and
caused parametric ampli�cation to happen within a shorter length of
�ber, as well as giving us a bigger maximum gain. These results will be useful in
optimizing the ampli�cation process with respect to the �ber length involved. |
