We investigate how embedding a metal nanoparticle with an optical emitter in a fiber modifies the emission properties of the emitter. By coupling the light emitter to a metal nanoparticle, we show that the emission rates, Purcell factor and quantum yield are increased due to the combined effects originating both from the confinement in the fiber and from the nanoparticle's plasmonic enhancement. We simulate numerically a fiber of permittivity ε = 4 containing a silver nanoparticle of radius 30 nm and find that the quantum yield enhancement can be up to 2.5 larger than in free space.","PeriodicalId":6587,"journal":{"name":"2016 10th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80046898","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}

The acoustic plane wave reflection from such an elastic-framed metaporous layer glued against rigid backing is studied. The analysis is performed by applying the multiple scattering theory in a dissipative Biot continuum while accounting for the fields scattered by the inclusion at the layer plane boundaries. It is shown that high broadband absorption of sound is achieved through the coupling of resonances of both the array and the shells with visco-thermal and elastic losses in the poro-elastic matrix. Moreover, the excitation of flexural resonances of the shells enable high-quality absorption of sound in the deep subwavelength regime. The semi-analytical approach of these multi-physical phenomena underlines the complex interactions between the scatterers and the poroelastic matrix, and allows the efficient computation of the fields.","PeriodicalId":6587,"journal":{"name":"2016 10th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics (METAMATERIALS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90306541","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}
