Abstract:

Two-pump fiber optical parametric amplifier (FOPA) with two-section highly nonlinear fibers is proposed and demonstrated, which has broad bandwidth, high and flat gain. Using the fourth-order dispersion coefficient of the fibers as a pivotal factor, the optimization of the gain characteristics of the FOPA with double pumps and two section fibers has been achieved. The results show that present FOPA has 424nm bandwidth with 62.46dB average gain and gain ripple less than 5dB.

Key words: fiber and waveguide optics fiber, optical parametric amplifier, two-pump, cascaded two-section fiber
