Fiber Optik Kabloda Meydana Gelen Raman Saçılmasının Analizi, sayfa: 257-265

Selim BOYDAK, Murat YÜCEL

Özet


Fiber optik kablo içerisinde ışık dalgaları ilerlerken, bir fotonun daha düşük enerjili fotona elastik olmayan saçılmasından dolayı, yayılan ışığın dalga boyundan farklı dalga boylarında, geri veya ileri yönlü, yeni ışık dalgaları oluşmaktadır. Bu ışık dalgaları bazı uygulamalarda istenmezken, bazı uygulamalarda ise yeni oluşan ışık dalgalarından faydalanılmaktadır. Bilinen en yaygın saçılma uygulamaları ise Brillouin ve Raman saçılmalarıdır. Bu saçılmalar kullanılarak fiber yükselteçler, fiber lazerler ve fiber sensörler üretilmektedir. Bu çalışmada, Raman saçılması teorik olarak incelenerek, tek ve çok kanallı Raman düzeneklerinde fiber boyuna bağlı olarak oluşan doğrusal olmayan Raman saçılmasının etkileri analiz edilmiştir.
