Abstract

In this study, temperature dependence of noise figure of C band erbium doped fiber amplifiers (EDFA) has beeninvestigated. To do this, EDFA is analyzed for 980 nm and 1480 nm pump wavelengths, -20 dBm and -30 dBminput signal powers in the temperature range between 0 °C and 60 °C. In the analysis, amplified spontaneousemission (ASE) effect was taken into account. The design is simulated using OptiAmplifier 4.0 software. Then,the experimental setup was established and the measurements were done, and for 980 nm pumping, thewavelength gaps that the effect of temperature negligible was obtained. Consequently, it has been found that,980nm pumped signal having lower noise figure than 1480 nm pumped signal.

Özet

Bu çalışmada C bandında çalışan erbiyum katkılı fiber yükselteçte (EDFA) gürültü faktörünün sıcaklıkbağımlılığı incelenmiştir. Bu amaçla C band EDFA, 0 °C ile 60 °C arasındaki sıcaklık aralığında, -20 dBm ve30 dBm’lik giriş sinyal güçleri, 980 nm ve 1480 nm pompa dalga boyları için analiz edilmiştir. Analizlerdeyükseltilmiş kendiliğinden yayınım (ASE) etkisi dikkate alınmıştır. Tasarım OptiAmplifier 4.0 yazılımıkullanılarak simüle edilmiştir. Daha sonra deneysel düzenek kurularak, ölçümler yapılmış ve 980 nm pompadalga boyu için sıcaklık etkisinin ihmal edilebileceği dalga boyu bölgelerinin bulunduğu görülmüştür. Ayrıca,980 nm’de pompalanmış sinyalin 1480 nm’de pompalanan sinyale göre daha düşük gürültü faktörüne sahipolduğu görülmüştür.
