During the last year, an important effort was carried out worldwide and significant improvements have already been achieved from a better design and fabrication of the active waveguide [1-4]. More recently, we have obtained polarisation insensitive GaInAsP/InP TWA's realized by gas source molecular beam epitaxy (GSMBE) with a high internal gain (28 dB) and a gain wavelength ripple of 3 dB for both TE and TM modes at a very low forward current of only 50 mA [5]. We present consolidated measurements on a large number of TWA'S with different structures, and in order to evaluate the tolerances on the technological parameters, we illustrate with a simple model, the variation of the polarisation sensitivity with gain.","PeriodicalId":308628,"journal":{"name":"Optical Amplifiers and Their Applications","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134107678","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}

Two kinds of amplification technique has been proposed: distributed amplification[2] and localized amplification[3]. The former offers much longer amplification spacing than the latter, because the former’s gain is distributed almost constantly along the fiber, while the latter’s gain is located locally, which leads to radiating dispersive waves[3]. In this paper, we report 20Gb/s optical soliton data transmission over a total distance of 70km utilizing two Raman amplifiers for fiber-loss compensation. The transmission distance corresponds to 19 soliton periods with our experimental parameters, and this value of 19 soliton periods is larger than any previously reported optical soliton data transmission. Raman gain as high as 10dB with forward and backward pumping by 160mW laser diodes was obtained by using a high Δn dispersion-shifted single-mode fiber as the transmission line. This fiber also has the advantage of transmitting optical solitons with relatively small input peak powers.","PeriodicalId":308628,"journal":{"name":"Optical Amplifiers and Their Applications","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132145614","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}
