우리는 중첩 규칙을 도입하고 펌프 간 에너지 전달을 설명하는 다중 파장 펌핑 라만 증폭기의 설계 절차를 개발했습니다. 펌핑 파장 및 전력 할당과 관련하여 요약됩니다. 시뮬레이션 결과와 실험 결과 간의 비교가 제시됩니다. 섹션 2에서는 라만 증폭기의 기본 사항을 검토합니다. 이 섹션에서는 다양한 광섬유에 대해 측정된 라만 이득 스펙트럼이 제시되고 스펙트럼 간의 차이가 논의됩니다. 3장에서는 중첩법을 도입하여 펌핑 파장 할당을 결정하는 방법을 설명합니다. 이 설계 방법을 통해 일부 최적화된 설계 예가 제시되며, 여기서 라만 이득의 피크 레벨은 모든 경우에 10 nm ~ 1525 nm(C-+L-밴드)의 파장 범위에 대해 1615 dB로 고정됩니다. 이러한 결과로부터, 더 많은 수의 펌프를 사용함으로써 더 나은 이득 평탄도를 얻을 수 있음을 확인하였다. 섹션 4에서는 실험 및 시뮬레이션 결과를 통해 펌프 간 에너지 전달이 이득 프로필을 어떻게 변경하는지 설명합니다. 본 절에서는 정밀한 수치해석을 수행하기 위한 시뮬레이션 모델링도 제시한다. 위의 논의로부터 설계 절차는 단순화될 수 있습니다. (1) 적절한 가중치를 사용하여 각 파장 차이에 의해 이동된 개별 라만 이득 스펙트럼을 대수 규모로 추가하여 원하는 복합 라만 이득을 얻을 수 있는 펌프 파장을 결정합니다. 그리고 (2) 정확한 수치 시뮬레이션을 통해 중량계수를 구현하기 위해 얼마나 많은 출력을 발사해야 하는지 예측합니다. 5장에서는 측정된 라만 이득과 중첩 이득을 비교하여 중첩 규칙과 펌프 간 에너지 전달 효과를 검증합니다. 두 이득 프로필의 일치는 다중 파장 펌핑 라만 이득 프로필에 각 펌프 파장에 의해 생성된 개별 이득 프로필만 포함되어 있음을 보여줍니다. 섹션 6에서는 이 논문을 마무리합니다.

Abstract: We have developed the design procedure of multi-wavelength pumped Raman amplifiers, introducing superposition rule and account for pump-to-pump energy transfer. It is summarized with respect to the pumping wavelength and power allocation. The comparisons between simulated and experimental results are presented. Section 2 reviews the fundamentals of Raman amplifier. In this section, Raman gain spectra measured for different fibers are presented and the difference among the spectra is discussed. Section 3 describes the way to determine the pumping wavelength allocation by introducing superposition method. By means of this design method, some optimized design examples are presented, where the peak levels of Raman gain are fixed to 10 dB for the wavelength range from 1525 nm to 1615 nm (C- plus L-band) in all cases. From these results, it is confirmed that better gain flatness can be obtained by using the larger number of pumps. Section 4 explains how the pump-to-pump energy transfer changes the gain profile by experimental and simulated results. In this section, simulation modeling to perform precise numerical simulation is also presented. From the above discussion, the design procedure can be simplified: (1) one determines pump wavelengths with which a desired composite Raman gain can be obtained by adding in logarithmic scale individual Raman gain spectra shifted by the respective wavelength differences with adequate weight factors. And (2), one predicts how much power should be launched in order to realize the weight factors through precise numerical simulations. Section 5 verifies the superposition rule and the effect of pump-to-pump energy transfer by comparing a measured Raman gain with a superposed one. The agreement of two gain profiles shows that the multi-wavelength pumped Raman gain profile contains only the individual gain profiles created by the respective pump wavelengths. Section 6 concludes this paper.
