Abstract
Fluorinated poly (ether ketone) bearing crosslinkable ethynyl group(FPEK-EP) has been investigated for low-loss polymeric optical waverguide devices. The molecular weight(Mn) and polydispersity of the polymer are determined as 6700 g/mol and and 1.76, respectively. Using a FT-IR and a DSC, curing properties of FPEK-EP are investigated. The film obtained by spin coating and then followed by thermal crosslinking at 250 ℃ for 2 h shows a good chemical resistance and a high thermal stability up to 480 ℃ under nitrogen. For the various curing conditions, the refractive indices and birefringence of the films are measured. The propagation loss of the single-mode channel waveguide is estimated to be less than 0.5 dB/cm at 1.55 ㎛.

고분자 광도파로 소자 제작을 위하여 열경화성 에티닐 페놀기를 가진 불소 치환 폴리에테르케톤 (FPEK-EP)을 합성하였다. 합성된 고분자의 분자량과 분자량 분포는 각각 Mn=6700 g/mol과 Mw/Mn=1.76이다. 레다-데의 경화 특서을 FT-IR 및 DSC로 관찰하였다. 회전도포와 250 ℃에서 2시간 동안의 열경화에 의해 얻어진 필름은 우수한 내화학성과 480 ℃까지의 높은 열안정서을 보여주었다. 경화온도에 따른 굴절률 및 복굴절 변화를 측정하였으며, 단일모드 광도파로를 제작하여 측정한 광도파손실은 1.55 ㎛의 파장에서 0.5 dB/cm이하였다.
