Abstract

We report theoretical and experimental investigation of a polarizer made of single mode side-polished fiber covered with a metal film. The influence of the metal film thickness and the refractive index of overlay on the device performance has been analyzed in terms of the normal mode theory. Based on the theoretical prediction, a polarizer with 40 ㏈ of polarization extinction ratio and 0.5 ㏈ insertion loss at optical communication wavelength has been realized.

본 논문은 금속박막과 결합된 측면 연마 단일 모드 광섬유를 이용한 편광기에 관하여 이론 및 실험 연구 결과를 보고한다. 금속 박막의 두께와 상부 유전체의 굴절률이 소자특성에 미치는 영향을 직교 모드이론으로 분석하였다. 이론적 예측을 토대로 광통신파장에서 편광 소멸비가 40 ㏈, 그리고 삽입 손실이 0.5 ㏈를 가지는 편광기를 구현하였다.
