Conventional erbium-doped fiber systems face significant challenges at 1590 nm due to low gain efficiency and amplified spontaneous emission (ASE) noise, highlighting the need for advanced excitation mechanisms. However, the lack of a detailed understanding of internal ASE-mediated excitation pathways has hindered the development of efficient laser sources with high gain and signal-to-noise ratio (SNR) in this spectral region. In this work, we investigate a novel ASE-induced quasi-cross-excitation transfer process (quasi-CETP) in erbium–ytterbium co-doped fiber (EYDF) systems. A coupled rate equation model is developed to capture ASE spectral evolution and its impact on population dynamics. The model reveals characteristic nonlinear spectral features and identifies three operational regimes — gain, quasi-saturation, and degradation — based on fiber length.

Determination of the important parameter values of these components for the design is quite essential in terms of cost and performance (e.g., gain, power conversion effect [PCE]). For TLS, signal wavelength and power; for PDF, PDF length, ion density, upconversion, numerical aperture, core radius, doping radius, and operating environment temperature; pump laser, pump power, and pump wavelength are the critical design parameters. Another factor that will improve the performance of the amplifier is the amplifier configuration. Although there are single-pass and double-pass PDFA studies in the literature, in this article, for the first time, the simulation, parameter optimization, and analysis of two-stage triple-pass PDFA (2P3S-PDFA) and three-stage triple-pass PDFA (2P3S-PDFA) are performed. The performances of 2P3S-PDFA and 2P3S-PDFA are compared in terms of gain and noise figure (NF). The optimum gain obtained for 2S3P-PDFA is 49,4 dB, and the NF at this point is around 6,5 dB. For 3S3P-PDFA, the optimum gain is 47,7 dB and the NF at this point is around 5,1 dB. When we look at the two amplifier types in general, 2S3P-PDFA performs better than 3S3P-PDFA in terms of optimum gain by around 1,7 dB. However, in terms of NF, 2S3P-PDFA has more NF than 3S3P-PDFA by around 1,6 dB. As a result of the optimization, it is seen that the 2S3P-PDFA system is more efficient than the 3S3P-PDFA system in terms of gain.</div></div>","PeriodicalId":19663,"journal":{"name":"Optical Fiber Technology","volume":"95 ","pages":"Article 104388"},"PeriodicalIF":2.7,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145047188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
