In this study, an amplified spontaneus emission (ASE) based L-band light source has been developed and characterized. Addressing limitations in current literature, a specific L-band ASE source with low ripple and high output power was designed. Using a double-pass bidirectional pumping configuration, the system employs a 17-meter Liekki Er30(4/125) high-concentration erbium-doped fiber (EDF) and two pump lasers (980 nm and 1480 nm) to achieve an L-band ASE spectrum with a bandwidth of 44 nm and a ripple of 3 dB and with a bandwidth of 31 nm and a ripple of 1.01 dB. The design significantly shortens the EDF length compared to other studies, providing an important cost advantage. This optimized L-band ASE source offers superior performance and is highly applicable in critical fields such as optical communication, sensor technologies, and the defense industry.

Bu çalışmada, kendiliğinden yükseltilmiş yayılım (ASE) tabanlı L-band ışık kaynağı geliştirilmiş ve karakterizasyonu yapılmıştır. Literatürdeki mevcut problemlere çözüm sunmak için düşük dalgalanma (ripple) ve yüksek çıkış gücü hedeflenmiş, özel bir L-band ASE kaynağı tasarımı gerçekleştirilmiştir. Çift geçişli çift yönlü pompalama konfigürasyonu kullanılarak, 17 metre uzunluğunda Liekki Er30(4/125) tipi yüksek konsantrasyonlu Erbiyum Katkılı Fiber (EKF) ve iki pompa lazer (980 nm ve 1480 nm) ile 44 nm bant genişliğine ve 3 dB dalgalanmaya ayrıca 31 nm bant genişliğinde 1.01 dB dalgalanmaya sahip bir L-band ASE kaynağı üretilmiştir. Bu özel tasarım sayesinde literatürdeki diğer çalışmalara kıyasla daha kısa EDF kullanılarak, toplam maliyet düşürülmüş ve yüksek performans elde edilmiştir. Çalışma, özellikle fiber optik haberleşme, sensör teknolojileri ve savunma sanayi gibi kritik alanlarda kullanılabilecek ASE ışık kaynaklarına yönelik önemli bir katkı sunmaktadır.
