Abstract

본 논문에서는 장주기 광섬유격자쌍을 이용하여 광섬유 Mach-Zehnder 간섭계(MZI)를 기계적인 방법으로 구현해 보았다. 제작한 간섭계의 장주기 광섬유격자쌍의 투과스펙트럼과 fringe spacing의 이론치과 실험치를 비교, 분석해 보았다. 그 결과, fringe spacing의 값은 이론치와 실험치가 비교적 잘 일치하는 것을 알았다. We have demonstrated mechanically induced Mach-Zehnder interferometers (MZI) based on a long-period fiber grating pair. The transmission spectra, the interference fringes, and the fringe spacing of the long-period fiber grating pairs have also been investigated experimently and analytically. The fringe spacings of the fabricated LPG pairs agree well with the theoretical results.
