Abstract

This paper presents design of a gain-flattened amplifier that covers an ultra-wide band including the well known optical S, C, and L bands. The amplifier has a split-band architecture, which amplifies the S, C, and L band signals in separate paths and then recombines the amplified signals for the output. We’ve used Erbium-doped fiber amplifier (EDFA) for the C band and L band amplification and used for a multi-pump fiber Raman Amplifier (FRA) for S band amplification. For the L band and C band EDFA design, cascade configurations that a gain flattening filter is inserted between the erbium doped fibers in order to suppress amplified spontaneous emission (ASE). The overall design was analyzed for ultra wide bandwidth and minimum ripple factor. Consequently, a gain of approximate to 24 dB, a maximum ripple factor of 0.3 dB, and total bandwidth of 120 nm are achieved.

Özet

Bu makalede iyi bilinen S, C ve L optik bandlarını kapsayan çok geniş bandlı bir kazancı düzleştirilmiş yükselteç tasarımı sunulmaktadır. Yükselteç parçalı band yapısına sahip olup, ayrı yollarda S, C ve L band sinyaller yükseltilir ve sonra yükseltilmiş sinyaller çıkışta birleştirilir. Biz C band ve L band yükseltmesi için Erbiyum katkılı fiber yükselteç (EKFY) ve S band yükseltmesi için çoklu pompalı bir fiber Raman yükselteç kullandık. C band ve L band EKFY tasarımı, kendiliğinden yükseltilmiş yayılmayı (KYY) bastırmak için erbiyum katkılı fiberlerin arasına kazanç düzleştirici bir filtre yerleştirilen kaskat yapıdadır. Bütün tasarım çok geniş band ve minimum dalgalanma faktörü için analiz edilmiştir. Sonuç olarak, yaklaşık 24 dB’lik bir kazanç, maksimum 0.3 dB’lik dalgalanma faktörü ve toplam 120 nm band genişliği elde edilmiştir.
