One potential performance limitation is due to the laser-induced optical degradations that occur during prolonged use. Waveguide fabrication process improvements can be applied, in conjunction with more modest laser power densities and longer laser wavelengths, to reduce or forestall such performance degradations. These methods, though important, may not be sufficient to solve the problem in many applications.","PeriodicalId":208165,"journal":{"name":"Seventh Topical Meeting on Integrated and Guided-Wave Optics","volume":"42 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":"130171162","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}

High efficiency can be achieved (Ref.1) by micro manipulating the fibre butted to the waveguide, while also taking steps to reduce modal field mismatch. Manipulating the fibre is however a complex and time-consuming operating which does not easily lend itself to multi-port devices. The use of silicon 'V' grooves (Ref.2) can aid fibre alignment and reduce the complexity of the operation while maintaining a high coupling efficiency. However, the component utilises two technologies and the alignment of multi-port devices face down onto the silicon surface poses problems. Problems may also arise from silicon and lithium niobate having different thermal expansion coefficients.","PeriodicalId":208165,"journal":{"name":"Seventh Topical Meeting on Integrated and Guided-Wave Optics","volume":"52 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":"122405114","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}
