We have jumped aver this classical limit in several nanophotonics technologies, such as in fabrication, in analysis and in imaging of samples at nanoscale, and have shown how light can interact with materials in a volume much smaller than the diffraction limits.","PeriodicalId":112256,"journal":{"name":"2008 International Nano-Optoelectronics Workshop","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127057653","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}
