표면 플라즈몬 광섬유 편광기의 제작 및 특성 조사
Fabrication and Characterization of Surface Plasmon Fiber-Optic Polarizers
초록
광섬유의 클래딩을 갈아내고 코어 가까이에 알루미늄 박막을 증착하여 표면 플라즈몬으로의 편광 선택적인 모드 결합 원리를 이용하는 광섬유 편광기를 제작하였다. 633nm, 830nm,
We fabricated fiber-optic polarizers utilizing polarization selective mode coupling between the guided mode of a fiber and the surface plasmon mode supported by a thin aluminium film deposited on the polished side of a fiber. AI thin films with various thicknesses were coated onto the 633 nm, 830 nm, 1.3 fJITI single mode fibers. The maximum extinction ratio was higher than 30 dB for most of the samples and the best result was 42 dB at 90 A film thickness, with 1.3 fJITI single mode fiber. The insertion loss ranged from 0.2 dB to 1.5 dB.1.5 dB.
