The main characteristics of the RE-doped dielectric nanoparticles (DNP), their density and mean diameter in the fibres are dictated by various parameters. This paper reports on progresses in the fine characterization of the nanoparticles, particularly their dimensions and composition, using nanoscale mass spectroscopy and molecular dynamics modeling, and alteration of the spectroscopic properties of the erbium ions embedded within the phospho-silicate DNP. These results permit to get more insight into the complex process of the DNP self-nucleation and growth during the fibre fabrication process. This fabrication route could have important potentials in improving rare-earth-doped fibre amplifiers and laser sources.","PeriodicalId":158783,"journal":{"name":"2012 Photonics Global Conference (PGC)","volume":"177 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134313021","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}

However, the atmospheric turbulence may degrade the interconnect performance due to the beam wander, signal scintillation, and beam broadening effects. In this paper, the experimental investigation of the impact of both moderate and comparatively strong atmospheric turbulence on the bit-error-rate (BER) performance of our proposed reconfigurable free-space card-to-card optical interconnects is presented. Experimental results show that the BER performance does suffer power penalties of ~0.5 dB and ~1.6 dB at BER of 10-9 under moderate and strong levels of turbulence respectively.","PeriodicalId":158783,"journal":{"name":"2012 Photonics Global Conference (PGC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121810299","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}

For this purpose, numerical solution of the Schrödinger equation is done in order to obtain the energy levels and their corresponding wave functions of electrons and holes in double semi-parabolic quantum well. Results are used to obtain the optical gain of this nanostructure. The effects of material parameters such as thickness of the barrier and width of the wells, Al composition and density of the carriers as well as external parameters such as temperature and pressure on the optical gain coefficient are investigated. Numerical results clearly show that by increasing of carrier concentration, wells width and decreasing the thickness of barrier, temperature and pressure the optical gain increases. Finally, we introduce the optimum structure of quantum well to obtain the maximum optical gain, which can be useful for quantum well laser designing.","PeriodicalId":158783,"journal":{"name":"2012 Photonics Global Conference (PGC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116923004","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}

A numerical comparison of the strain field along mPOFBG - AOM and the similar structure with SMFBG-AOM was presented, showing that the strain field amplitude is higher along the mPOFBG due to its smaller mechanical stiffness. The obtained results can be used in the development of fine-tuned optical filters using low voltage sources and low frequency regimes, to obtain tunable optical filters and to control the shape of the spectrum. Studies of the behavior in different gratings (such as phase shifted and long period gratings) for photonic applications, such as tunable notch filters or tunable cavities, are in progress. It can potentially be applied on tunable optical filters for POF transmission.","PeriodicalId":158783,"journal":{"name":"2012 Photonics Global Conference (PGC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120935780","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}
