Abstract

기계적으로 유도된 소자형 장주기 광섬유격자를 처음으로 제작해 보았다. 본 연구의 장주기 광섬유격자 소자는 제작이 용이하며. 다른 광 소자나 시스템에 적용 또는 장착이 가능하다는 장점을 가지고 있다. 또한, 제작된 장주기 광섬유격자 소자는 격자 제작시 중심파장과 투과손실을 가변할 수 있는 특징을 가지고 있다. 장주기 광섬유격자 소자의 제작원리를 살펴보고, 제작된 장주기 광섬유격자의 파장가변 특성과 압력에 따른 투과특성을 실험해 보았으며, 장주기 광섬유격자 소자를 EDFA의 이득 평탄화 실험에 적용해 보았다. For the first time to our knowledge we have developed compact mechanically-induced long-period fiber grating devices which have an excellent tunability in the center wavelength and the depth of the notch. The compactness and ease to tune allow us to include them in other optical devices or systems. The devices were characterized by measuring their transmission spectra with different grating periods and applied pressures. We have also demonstrated the EDFA gain flattening using the mechanically-induced long-period fiber grating devices.
