Plastic optical fibre is used to measure the bending angle by measuring the changes of light intensity using tilt angle loss measurement approach. To define the bending range of the sensor configurations under investigation, the fibre was bended at several bending angle for a 30 second period purposely to reduce the effect of light source fluctuation and drift in measurement. It was found that, with the use of dual input source fibres, the bending angle range can be extended at almost twice angle range than the single input fibre but with a lower output resolution.","PeriodicalId":308672,"journal":{"name":"2013 IEEE 4th International Conference on Photonics (ICP)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133983605","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}

Instead, the EO modulator can also be employed as sensing instrument with some modification. In this paper, we demonstrate the performance study of a polymer EO phase modulator compared with the commonly used waveguide material LiNbO3 to obtain better low insertion loss and length extension. Both parameters are substantial for biosensing applications such as biomedical equipment to detect human body response.","PeriodicalId":308672,"journal":{"name":"2013 IEEE 4th International Conference on Photonics (ICP)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122261426","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}

However in most cases, evanescent field is not maximized and thus the performance of the sensor is not optimized. It is the aim of the paper to optimize the silicon nitride linear waveguide through simulation by using 3D FD-BPM. The resultant investigation shows that evanescent field is maximized at TM polarization, 0.9μm thickness and 4μm width waveguide. Besides, result also shows that TM-polarization results in 15.5 times stronger evanescent field at optimized physical dimension compared to TE polarization.","PeriodicalId":308672,"journal":{"name":"2013 IEEE 4th International Conference on Photonics (ICP)","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115110277","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}
