초록
본 논문에서는 포토폴리머에 기록된 Bragg 회절 격자의 열적 특성을 측정하였다. 532 nm의 Nd:YAG 레이저를 이용하여 DuPont HRF-150-38 필름에 홀로그램 격자를 기록하고, 온도 노출 조건에 따라 회절효율을 측정하였다. 열 노출 후 홀로그램 기록에서는 100℃이하에서 70% 이상의 높은 회절 효율을 보인 반면 더 높은 온도에서는 급격히 떨어졌다. 홀로그램 기록 후 열 노출에서는 UV 정착 효과에 따라 100℃까지는 10% 정도의 효율 증가를 보여주었지만, 120℃이상에서는 홀로그램이 지워지는 현상이 관찰되었다.
Abstract
This paper presents the thermal characteristics of a Bragg grating recorded in photopolymer. We record hologram gratings using a 532 nm Nd : YAG laser in DuPont HRF 150-38 photopolymer films and analyze the diffraction efficiency versus thermal exposure conditions. For the case of recording after heating, the diffraction efficiency of the hologram is more than 70% at 100 ℃ but is decreased exponentially at temperatures over 100℃. It is observed in the recording before heating that the diffraction efficiency of the hologram fixed by a UV light is increased to approximately 10% at 100℃, but the holograms are erased at temperatures over 120℃.
