The microlens structure is made of soft polymer and its substrate is made much thinner than the lens to reduce the stress on the lens when it is stretched on a curved surface. A low-temperature fabrication process is developed to reduce the stress in the polymer. The focal length f can be varied between -14 mm and 33 mm. The lens can resolve 11.30 line pairs per mm at f = 33 mm according to a 1951 USAF resolution chart test and the response time of the lens is approximately 50 ms.","PeriodicalId":347863,"journal":{"name":"2012 International Conference on Optical MEMS and Nanophotonics","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128121696","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}

Optofluidics aims in manipulating light and fluid at microscale and exploiting their interaction to create highly versatile devices that have significant scientific interests in many areas. The novelties of the integrated optofluidics are two-fold. First, fluids can be used to carry substances for analysis in highly sensitive optical micro-devices. Second, fluids can also be exploited to control light, making them tunable, reconfigurable and adaptive. It is a new breakthrough research area that provides new solutions and opportunities for a wide range of traditional photonic devices, allowing tuning and reconfiguration at the micrometer scale by using microfluidic manipulation. This new innovation allows scientists and researchers to tackle many classical problems with new tools and new research ideas. In this paper, the state-of-the-art of optofluidic research is reviewed with breakthrough innovations in optical and photonic devices, including the high potential applications of optofluidics in biophysical, biochemistry and biomedical studies.","PeriodicalId":347863,"journal":{"name":"2012 International Conference on Optical MEMS and Nanophotonics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127321971","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}
