Abstract
Fiber-optical parametric amplifier has currently drawn interest of research for evolving efficient broadband amplification in optical communication network. This paper presents dispersion flattened highly nonlinear fiber’s role as a fiber optic parametric amplifier. This study has been carried out with single pump in the novel highly nonlinear ultra-flattened dispersion shifted fiber (HN-UFF) that was designed by us earlier. This paper also discusses the impact of length of such HN-UFF, pump signal power, input signal power and pump signal wavelength on fiber optic parametric gain. Simulation results reveal that a high value of fiber optic parametric gain of about 15 dB and respective bandwidth of over 600 nm can be achieved by properly utilizing the high nonlinearity and ultra-flattened dispersion of the HN-UFF. Since parametric amplification follows the Four wave mixing technique, in addition to good amplification, an effective wavelength conversion can also be carried out over a wide range of 600 nm in future.
