광섬유 브래그 격자를 이용한 파장가변 형 전광 필터의 온도특성에 관한 연구 = A Study on the Thermal Characteristics of Tunable All-Optical Filter Using Fiber Bragg Grating

다국어 초록 (Multilingual 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 $600^{\circ}C$, but it is difficult to tune a Bragg center wavelength over this temperature.
