An optical soliton is a pulse of light in a fibre produced by a balance of group velocity dispersion and cubic non-linearity. Twenty years after its discovery, optical solitons are rapidly attracting interest from technical as well as scientific communities thanks to progress in coherent light source, fibre amplifier and other photonic devices and surprising agreement of the theoretical predictions with experimental observations.","PeriodicalId":130003,"journal":{"name":"Quantum Optics: Journal of The European Optical Society Part B","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129507515","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}

The corresponding Mandel Q parameter attains highly non-classical values very close to its optimum of Q=-1 and thus is significantly smaller than for the resonant case or the regularly pumped laser Q>- 1/2 . Subsequently we show that inhomogeneous Doppler broadening of the atomic lines does not drastically influence the non-classical behaviour of the intracavity field as long as the laser is operated sufficiently far above threshold.","PeriodicalId":130003,"journal":{"name":"Quantum Optics: Journal of The European Optical Society Part B","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128726317","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}
