It has also been reported that when the signal wavelength is located exactly at the zero dispersion wavelength, the mixing of the signal with the spontaneous emission from the optical amplifiers will produce four-wave mixing sidebands.[3] However, in the practical systems, the fiber chromatic dispersion varies along the long transmission path and may alleviate the effect of the four-wave mixing.

The EDF will most likely be used for preamplification, power boosting, linear repeating because of its advantages of polarization insensitivity, extremely low ”facet” reflectivity, good noise and saturation output power properties. However, the EDF amplifier is limited in versatility: In the semiconductor laser amplifier (SCLA), light amplification is effected by the coupling between the photon field and inverted electron population system, implying that the quasifermi level separation provides an electronic means of monitoring the optical field. Further, since the spontaneous recombination time is of the order of ns, the optical field can be detected (simultaneously with amplification), frequency converted and gated up to bandwidths of ≈ 1 GHz. In the EDF, there is no analog to the electrooptic interface (although the monitoring might be possible to perform optically) and the spontaneous recombination time is on the order of ms. Hence, the SCLA offer unique possibilities, and all of the above functions can be implemented by one single generic structure which is integrable, in contrast to the EDF. But it should also be noted that the ns time scale introduces severe crosstalk problems in multichannel systems.","PeriodicalId":308628,"journal":{"name":"Optical Amplifiers and Their Applications","volume":"387 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134437505","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}

They may be used as filters in switching network or as receiver preamplifiers in multichannel direct detection systems [1].

For such applications it is important to understand the dynamic behaviour of DFB amplifiers when they are used in high speed systems. Especially, it is interesting to know the influence of the very narrow gain spectrum on short optical pulses.","PeriodicalId":308628,"journal":{"name":"Optical Amplifiers and Their Applications","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125105570","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}

It has recently been realized, however, that such constraints may be overcome using Er3+-doped fiber amplifiers. A numerical analysis [1],[2] has shown that buses with periodic amplification should be capable of supporting large numbers of nodes, even in the presence of saturating signals. Moreover, there is experimental evidence [3] that bus networks with uniformly distributed amplification generate low levels of amplified spontaneous emission (ASE). We here present a simple analysis yielding closed-form expressions showing that the amplified bus can indeed support thousands of nodes, that it can span thousands of kilometers (fiber dispersion and nonlinearity permitting), and that this excellent noise performance results from the slow growth of ASE in low-gain amplifying structures. To support large numbers of nodes, however, the bus’s gain must be well matched to its loss.","PeriodicalId":308628,"journal":{"name":"Optical Amplifiers and Their Applications","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131485412","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}

Many experiments have been published demonstrating both the long-distance and multi-channel capability of fiber amplifier-based systems. Most experiments have used conventional direct detection systems [1,2]; but some experiments, including a record transmission distance experiment, have used coherent detection systems [3,4]; and models of both systems have been developed. This paper will compare the two systems under the same conditions using both experiments and models. We will emphasize a practical comparison by using a direct detection regenerator from AT&T’s commercial, 1.7 Gb/s system and a shelf-mounted, coherent detection regenerator from a recent AT&T field trial [5]. We will also emphasize a direct comparison by using transmitters of the same wavelength and identical optical paths including erbium-doped fiber amplifiers.","PeriodicalId":308628,"journal":{"name":"Optical Amplifiers and Their Applications","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133813439","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}
