Linear SOI waveguide arrays were fabricated on BESOI (bonded and etched-back SOI) material with a silicon top-layer of H = 4 /spl mu/m. We used standard contact lithography for patterning and a commercial RIE system for waveguide and facet etching. We studied different process flows (facet-first and rip-first), different masking materials and loading effects on the wafer. The surface of the facets was characterized by high resolution scanning electron microscopy (SEM). The additional coupling loss introduced by the process flow and by the etching conditions as well as the impact of the two on uniformity of the waveguide transmission were quantified by means of fiber-to-fiber optical measurements (at 1.55 /spl mu/m).","PeriodicalId":445290,"journal":{"name":"Proceedings of 2005 IEEE/LEOS Workshop on Fibres and Optical Passive Components, 2005.","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122582873","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}

It is demonstrated that an optically-driven fiber ring resonator is sensitive to strain, attenuation and the index of refraction of the fiber. In order to recover the measurements of a chaotic sensor like the one proposed in this paper a theoretical model is required. This model is presented and discussed in the paper. It reveals the dependencies of the geometrical parameters of the strange attractor on the optical configuration of the fiber ring. Using this model, the measurement of both strain and attenuation is simulated in this work.","PeriodicalId":445290,"journal":{"name":"Proceedings of 2005 IEEE/LEOS Workshop on Fibres and Optical Passive Components, 2005.","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126484297","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}
