It is established that maximum values of the frequency width of the response band and possibilities of realization of high-speed regimes at signal transmission in information systems are obtained at the central region of the gain band. Growth of the direct component of the pump current results in increasing the response bandwidth. At typical system parameters (in the region of 1.5 µm) the maximum value of the response bandwidth can be up to ≈ 40 GHz.","PeriodicalId":117420,"journal":{"name":"2010 10th International Conference on Laser and Fiber-Optical Networks Modeling","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122880135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
