The Al-based structures have been obtained by a suitably developed growth procedure with the aim of increasing island density and engineering the absorption spectrum and the energy band profile in the near infrared region. Along with tunability of the confined electron energy levels, the proposed Al-based structures exhibit transport features, such as reduced edge recombination losses and lower reverse saturation current density with respect to the InAs/GaAs QD system, which can be useful for enhancing device performances.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116196275","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 inner surface of the fiber has been functionalized using PNA probes, OligoNucleotides mimic that are well suited for specific DNA target sequences detection. The measurements of fluorescence have proved the successful hybridization. After the hybridization has occurred, oligonucleotide functionalized TiO2 Nano Particles (TiO2NPs) were infiltrated and used to form a sandwich-like system to achieve signal amplification. The numerical analysis is essential to evaluate physical parameters of the functionalized fiber: the refractive index and the thickness of the layer. The calculated shift of the reflected high order mode Bragg grating has a good agreement with the experimental result.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"74 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130824593","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}

We investigate the optical properties and the sensing capabilities of a highly disordered system of silica nanowires decorated with spherical gold nanoparticles. These systems present unique light trapping properties due to the combination of the highly diffusivity of transparent silica nanowires, with the selective absorption resonances given by Au nanoparticles deposited along the wires. The enhanced absorption at the LSPR resonances makes our materials excellent candidates to build plasmonic biosensors. The optical properties of these systems have been theoretically investigated by developing appropriate 2D finite element simulations. As proof of concept we have successfully tested the ability of the NP/NW forests to act as refractive index sensors and to detect biomolecular binding of the Protein BSA - AntiBSA bonding.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132900190","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}

Compared to standard DPP-BOTDA, the balanced-detection DPP-BOTDA method allows to retrieve the differential Brillouin gain in real time, i.e. without the need of post-processing differentiation, therefore allowing its combination with the Slope-Assisted BOTDA technique. The experimental mode shape of the first resonance of the aluminum plate is compared to numerical results based on a finite-element analysis (FEA), demonstrating that the proposed technique is well suited to perform the modal analysis of a vibrating structure.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128849003","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}
