The experimental results have shown that the incident laser beam's collimation was maintained after coupling to a planar waveguide. A characterization set-up using two prisms was designed for measuring transmission characteristics of integrated structures and eventually planar waveguides in the visible or in the IR range. Since a reasonable overall optical efficiency of 10% has been demonstrated for this set-up, the prism approach can be eventually utilized in Bragg Grating structures characterization.","PeriodicalId":366119,"journal":{"name":"2009 Asia Communications and Photonics conference and Exhibition (ACP)","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127275388","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}
