넓은 동적 범위와 우수한 잡음 성능을 모두 갖춘 자동 레벨 제어(ALC) 에르븀 도핑 광섬유 증폭기(EDFA)를 구현하기 위해 자동 전력 제어(APC) 방식과 가변 감쇠 기울기 보상기(VASC)를 적용한 EDFA를 제안합니다. . VASC는 직렬로 연결된 두 개의 비대칭 마하젠더 간섭계(MZI)로 구성되며 열 광학(TO) 히터가 각 MZI의 암에 부착됩니다. TO 히터에 공급되는 전력을 조정하면 작동 파장 대역 5nm에 걸쳐 거의 선형에 가까운 감쇠 기울기를 플러스 마이너스 30dB 이상 변경할 수 있습니다. APC 방식과 VASC를 적용한 EDFA는 최대 20dB의 넓은 동적 범위와 0.7dB의 작은 출력 전력 변화를 나타내어 APC 방식과 가변 광 감쇠기(VOA)를 적용한 EDFA와 맞먹는 수준이다. ). VASC를 적용한 EDFA의 잡음 지수(NF)는 입력 전력을 4.1dB 증가시키면서 약 20dB 저하되는 반면, VOA를 적용한 EDFA에서는 입력 전력을 7.3dB만 증가시키면 약 15dB 저하되는 것으로 나타났다. VASC를 사용하는 EDFA는 잡음 지수 저하를 줄이면서 더 넓은 동적 범위에서 ALC 작동을 실현할 수 있습니다. VASC를 적용한 EDFA에서는 1.1 ms의 상승/하강 시간으로 입력 신호 레벨이 -23 dBm/ch에서 -18 dBm/ch 사이에서 변경되었을 때 전력 편위가 8 dB 미만으로 억제되었습니다.

Abstract: In order to realize automatic-level-controlled (ALC) erbium doped fiber amplifiers (EDFAs) with both wide dynamic range and good noise performance, we propose EDFAs employing the automatic power control (APC) scheme and a variable attenuation slope compensator (VASC). The VASC consists of two asymmetrical Mach-Zehnder interferometers (MZIs) concatenated in series and thermo optic (TO) heaters are attached to the arms of each MZIs. By adjusting the electric power supplied to the TO heaters, an almost linear attenuation slope can be varied by plus minus 5 dB or more over the operational wavelength band of 30 nm. The EDFA employing the APC scheme and the VASC has exhibited a dynamic range as large as 20 dB with the output power variation as small as 0.7 dB, which is as good as that of the EDFA employing the APC scheme and a variable optical attenuator (VOA). The noise figure (NF) of the EDFA employing the VASC was degraded about 4.1 dB with increasing the input power by 20 dB, while it was degraded about 7.3 dB with increasing the input power by only 15 dB in the EDFA employing the VOA. The EDFA employing the VASC can realize the ALC operation over a wider dynamic range with reduced noise figure degradation. In the EDFA employing the VASC, the power excursion was suppressed to less than 1.1 dB, when the input signal level was changed between -23 dBm/ch and -18 dBm/ch with the rise/fall time of 8 ms.
