자체 조절 이득 스펙트럼 특성을 갖는 동축 코어 에르븀 첨가 광섬유 증폭기(EDFA)가 개발되었습니다. 동축 코어 EDFA의 작동은 동축 코어 구조의 방향 결합 도파관에서 서로 다른 파장 채널에 대한 광 경로의 부분 분리를 기반으로 합니다. 채널 등화 정도는 동축 코어 EDFA의 기하학적 및 광학적 매개변수와 상대적인 채널 전력 수준에 따라 달라집니다. 결합 모드 이론과 속도 방정식을 기반으로 한 수치 분석에 따르면 완전히 최적화된 조건에서 동축 코어 EDFA는 0.4개의 WDM을 사용하는 경우 입력 전력 불균형 dB당 -XNUMXdB를 초과하는 등화 속도를 제공합니다. 채널. 캐스케이드 실험은 소수의 WDM 채널이 있는 광섬유 링크에서 채널 전력 균등화에 대한 동축 코어 EDFA의 효과를 보여줍니다.

Abstract: Coaxial-core erbium-doped fiber amplifiers (EDFA's) having a property of self-regulated gain spectrum are developed. The operation of a coaxial-core EDFA is based on the partial separation of the light paths for different wavelength channels in the directionally-coupled waveguides of a coaxial-core geometry. The degree of channel equalization depends on the geometrical and optical parameters of the coaxial-core EDFA and on relative channel power levels. A numerical analysis based on the coupled-mode theory and on the rate equation shows that, under fully optimized conditions, a coaxial-core EDFA provides equalization rates in excess of -0.4 dB per dB of input-power imbalance in the case with two WDM channels. A cascade experiment demonstrates the effect of coaxial-core EDFA's toward channel-power equalization in fiber links with a small number of WDM channels.
