Abstract

In this study, gain dependence in Hafnium-Bismuth-Erbium co-doped fiber amplifier (HfBiEDFA) on pumping configuration and active fiber length were analyzed experimentally. Gain and signal output power characteristics of the heavily co-doped HfBi-EDFA pumped with a 980 nm pump laser were experimentally obtained for different pumping methods (forward, backward and bidirectional) as functions of pump power, signal input power, and wavelength. During the study, 0.3 m and 1.1 m long HfBi-EDF and a signal input power of -30 dBm at 1550 nm were used, and the pump power was increased from 60 mW to 204 mW. A moderate gain of over 11 dB was obtained in forward and backward pumping configurations but the gain has remained at around 7 dB in the bidirectional pumping configuration. The spectral gain measurements were realized across a 1520 nm - 1605 nm wavelength range, and the forward and backward pumping configurations resulted in the best gain values at 1532 nm with a gain of around 17 dB. It was also shown that when the HfBi-EDF length is 0.3 m, optical amplification in the C band is achieved. For the fiber length of 1.1 m, the gain spectrum shifts towards the L band.

Özet

Bu çalışmada, Hafniyum-Bizmut-Erbiyum ortak katkılı fiber yükselteçte (HfBi-EDFA) kazancın pompalama konfigürasyonuna ve aktif fiber uzunluğuna bağımlılığı deneysel olarak analiz edilmiştir. 980 nm pompa lazeri ile pompalanan, yoğun katkılı HfBi-EDFA'nın üç farklı pompalama konfigürasyonu için (ileri, geri ve çift yönlü pompalamalı) kazanç ve sinyal çıkış gücü performansı, pompa gücü, sinyal giriş gücü ve dalga boyunun fonksiyonu olarak analiz edilmiştir. Deneysel çalışmada, aktif kazanç ortamı olarak 0,3 m ve 1.1 m uzunluklarında yoğun katkılı HfBi-EDF kullanılmış; sinyal giriş gücü 1550 nm dalgaboyunda -30 dBm'de sabit tutularak, pompa gücü 60 mW-204 mW aralığında değiştirilmiştir. İleri ve geri yönlü pompalamalı HfBi-EDFA için 11 dB'in üzerinde orta düzeyde bir kazanç elde edilirken, çift yönlü pompalamalı HfBi-EDFA için kazanç seviyesi 7 dB civarında kalmıştır. Üç farklı pompalama konfigürasyonu için kazanç spektrumu ölçümleri 1520 nm - 1605 nm dalga boyu aralığında gerçekleştirilmiş, ileri ve geri pompalamalı HfBi-EDFA konfigürasyonları için 1532 nm'de 17 dB civarında en iyi kazanç değeri elde edilmiştir. Bu çalışmada ayrıca, HfBi-EDF uzunluğu 0,3 m olduğunda C bandında optik amplifikasyonun sağlandığı gösterilmiştir. 1,1 m'lik aktif fiber uzunluğu için ise kazanç spektrumu L bandına doğru kaymaktadır.
