They are efficient and useful tools also in biochemical assays, providing high performance in sensitivity and selectivity of measurements. In this work, we developed a label-free biosensor based on a two-dimensional photonic crystal patterned on a large area silicon nitride membrane that operates in the visible spectrum for the detection of proteins. The biosensor has been preliminarily tested in solutions of different refractive index, showing as expected a shift of the resonance in the reflection spectrum.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"14 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":"128093496","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 model was used to calculate the radial distribution of the scintillation photons, in order to speed up the design of the optical system. The proposed method allows to generate a random distribution of coordinates of the scintillation photons similar to that obtained with a Monte Carlo simulation but the procedure is considerably faster. The radial light distribution of the proposed model is in good agreement with the GEANT4 Monte Carlo simulation. The computational time of the photon coordinate generation for our method is four order of magnitude smaller with respect to the GEANT4 Monte Carlo simulation.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"46 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":"133180037","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}

Our attention is focused on a micromegas (an abbreviation for “micro mesh gaseous structure” (MM)), that is a micro patter gas detector to be applied in Large Hadron Collider (LHC) at European Organization for Nuclear Research (CERN) in the ATLAS experiment. One mandatory issue for the correct operation of the MM detector is a precise monitoring of its panels' flatness/deformation. To this aim, FBG real-time sensing technology is proposed for its capability to meet important requirements in terms of radiation hardness and insensitivity to magnetic fields and to offer local strain detection with high sensitivity (resolution of 1 με). As a demonstrative target, in this work some FBG sensors have been integrated (surface attached) with a miniature MM detector support panel in order to investigate their potentialities/capabilities in detecting local strain and thus bending. The obtained experimental results confirm that FBG sensors, that tolerate high radiation, are able to monitor deformation and curvature in accord with high energy physics requirements.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"30 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":"127683835","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}

In particular, a waveguide Bragg serpentine (BSRR), which behaves like a Bragg grating, is proposed. This device shows a spectral response characterized by a photonic band gap (PBG) behavior. Very close to the band gap edges, it exhibits split resonant modes coupled by the grating effect and having a splitting magnitude equal to the PBG spectral extension. By changing the effective refractive index, the photonic band gap splitting magnitude varies. Otherwise, the PBG extension still remains almost unvaried if the length of the device changes, because only the Bragg wavelength will shift. By exploiting this physical principle, these devices can be proved as high sensitivity refractive index photonic sensors, based on a sensing mechanism almost immune to the length variations generated from any environmental perturbation.","PeriodicalId":125701,"journal":{"name":"2014 Fotonica AEIT Italian Conference on Photonics Technologies","volume":"45 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":"130471906","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}
