Estimation of Variables Affecting Parametric Amplification in Fiber Optics

Abstract

Four-wave mixing (FWM) is referred to as a parametric process and one of useful applications is using it for optical signal amplification. One of advantages of fiber optics parametric amplifiers (FOPAs) over broadly used conventional EDFAs (erbium doped fiber amplifiers) is the ability to tune the amplification wavelength region of FOPA which is not possible with EDFA, whose gain bandwidth is limited between 1530 and 1565 nm [2]. This feature of FOPAs makes it possible to utilize them for light amplification in S (1460 to 1530 nm) and L (1565 to 1625nm) optical bands
