Abstract
In this paper, the thermal characteristics of a tunable all-optical fiber Bragg grating(FBG) filter was investigated by numerical analysis. From the results, it is possible to tune a Bragg center wavelength along temperature variation because a Bragg center wavelength is varied linearly according to its operating temperature, however, the reflectivity of a Bragg center wavelength was reduced over a limited high temperature. Accordingly, it is possible to obtain the stability of a tunable all-optical FBG filter within
본 논문에서는 파장가변 형 전광 FBG 필터의 온도 특성을 수치해석을 통하여 고찰 하였다. 수치해석 결과로부터, FBG에 가해지는 온도에 따라 브래그 중심파장이 선형적으로 이동함으로 중심 파장을 가변 시킬 수 있음을 알 수 있으나, 브래그 중심파장의 반사도는 고온의 영역에서 감소하게 된다. 따라서,
