Although the Raman gain increases in the slow-light regime, the nonreciprocity is smaller. Thus, it is interesting that Raman-pumped optical isolators benefit from slow-light operation. Significant reductions in pump power and/or device length are found to be possible. © 2011 The Institution of Engineering and Technology.en1350-911X20112513921393IETTechnikIngenieurwissenschaftenElectrical Engineering, Electronic EngineeringJournal Article10.1049/el.2011.3068Journal Article
