Abstract

In order
to obtain analytical gain expression in Brillouin optical Fiber Amplifiers
(BFAs), coupled intensity equations describing the interaction of pump and
stokes waves must be solved simultaneously. For long optical fibers, although
fiber loss is responsible for the pump depletion and nonnegligible effect, for
short optical fibers less than 2 km, its effect can be discarded. In this
paper, we provide an accurate analytic expression for the BFA gain for fiber
lengths less than 2 km by discarding the optical fiber loss and show results of
experimental validation.

2 km'ye kadar uzunluktaki Brillouin Fiber Kuvvetlendirici kazancının analitik ifadesi

Abstract

Brillouin
Fiber Kuvvetlendirici (BFK) kazancının analitik ifadesini elde etmek için,
pompa ve Stokes dalgalarının etkileşimini tanımlayan denklemlerin çözümü
gerekmektedir. Uzun optik fiberler için fiber kaybı, pompa lazerini tüketmesi
nedeniyle ihmal edilemez bir parametre olmasına rağmen, 2 km'den kısa BFK’ de
etkisi ihmal edilebilir. Bu makalede, optik fiber kaybı ihmal edilerek, 2
km'den daha kısa optik fiberler için BFK kazancı analitik olarak ifade
edilerek, bu ifadenin doğruluğu deneysel olarak gösterilmiştir.
