摘　　要：光纤参量放大器在当今高速WDM光纤通信系统中有广泛的应用前景,宽带宽是其主要特性之一,本文在分析诸如光纤的色散平坦斜率、零色散波长及双折射因素对光纤参量放大器增益带宽的影响的基础上,论述了拓宽增益带宽的几种方法和设计技术。Fiber optical parametric amplifier has extensive applications in WDM optical fiber communication systems, gain bandwidth broadening is one of its most important specialities. In this paper, the effects on the fiber optical parametric amplifier＇s gain bandwidth which come from slope of the dispersion, zero-dispersion wavelength and birefringence are introduced. Furthermore, we also discuss several techniques to broaden the gain bandwidth.
