ELEKTRİK ARK TEKNİĞİ İLE UZUN PERİYOTLU FIBER IZGARA TASARIMI VE ÜRETİMİ

Elektrik ark yöntemi, fiberin mekanik ortamda kaydırılırken elektriksel ark deşarjları ile yazıldığı, esnek, uygulaması kolay ve ekonomik bir tekniktir. Bu çalışmada, elektrik ark yöntemi ile uzun periyotlu fiber ızgarasının (LPFG) üretilmesi için deneysel bir düzenek önerilmiş ve üretime etki edebilecek tasarım değişkenleri araştırılmıştır. Tipik bir LPFG nin üretildiği ilk deneysel çalışmanın ardından, LPFG kullanarak erbiyum katkılı fiber yükselticinin (EDFA) kazanç spektrumunun düzleştirilmesi üzerine araştırmaya yön verilmiştir. Araştırma sonuçları ve deneysel bulgular, elektrik ark tekniği ile üretilen LPFGlerin EDFAnın kazanç spektrumunu düzleştirici yönde olumlu etki sağlayabileceğini göstermiştir.

DESIGN AND PRODUCTION OF LONG PERIOD FIBER GRATING USING ELECTRICAL ARC TECHNIQUE

The electrical arc technique is a flexible, easily applicable and cost-effective technique, in which fiber is written to form a grating structure using electrical arc-discharges during mechanical motion. In this study, an experimental set up is proposed to product long period fiber gratings (LPFG) and the design parameters that affect the process are investigated. After the first experimental study on production of a typical LPFG, the research is directed on smoothing the gain spectrum of erbium doped fiber amplifiers using LPFG. The research results and experimental findings demonstrate that LPFGs manufactured using electrical arc technique can provide positive a effect on smoothing the gain spectrum of an EDFA.
