50GHz 채널 간격 10Gb/s DWDM 시스템에 적용하기 위해 분산 감소 광섬유 브래그 격자(FBG)를 시연합니다. 이 새로운 FBG는 굴절률 프로파일에 최적화된 코사인 확장 계열을 적용하여 설계되었습니다. 굴절률 프로파일의 10 π 위상 변이는 정사각형 필터링 특성과 선형 위상 응답을 모두 실현하여 반사 대역폭의 그룹 지연 변화를 줄입니다. 새로운 설계에 따라 제작된 FBG는 테스트되었으며 인접 채널에 대해 30dB 이상의 격리와 반사 대역폭의 10psec 미만의 그룹 지연 변화를 보여줍니다. 이러한 작은 분산으로 인해 10Gb/s 전송 성능이 크게 향상됩니다. 새로운 FBG의 전력 패널티는 기존 FBG의 1/6로 억제되었습니다. 또한, 코사인 확장 계열을 적용하여 구현된 대칭형 굴절률 프로파일은 이러한 광학 특성이 빛의 발사 방향에 의존하지 않음을 보여줍니다. 이러한 결과를 바탕으로 이 새로운 설계는 10Gb/s DWDM 시스템에 사용되는 ADM에 적합한 FBG를 제공합니다.

Abstract: For the purpose of applying to 50 GHz channel spacing 10 Gb/s DWDM systems, the dispersion reduced fiber Bragg gratings (FBG) is demonstrated. This new FBG is designed by applying in optimized cosine expansion series to the refractive index profile. The 10 π-phase shifts in the refractive index profile realize both square filtering characteristics and linear phase responses resulting in reducing group delay variation in the reflective bandwidth. The FBG, fabricated according to the new design, is tested and shows more than 30 dB isolation for the adjacent channel and less than 10 psec group delay variation in the reflective bandwidth. This small dispersion leads to vast improvement of 10 Gb/s transmission performance. The power penalty of the new FBG is suppressed to 1/6 of that of conventional FBG. Furthermore, the symmetrical refractive index profile, realized by applying a cosine expansion series, shows that these optical characteristics have no dependence of the light launching direction. From these results, this new design offers an FBG suitable for the ADM used in 10 Gb/s DWDM systems.
