Through different research areas, we demonstrate the possibilities offered by new fiber designs and alternative methods of manufacturing. Photonic Band Gap fibers reconcile diffraction limited beam and large mode area with low bending loss. 80 % slope efficiency is demonstrated together with a robust propagation allowing the fiber to be tightly bent until wounding radii as small as 6 cm. Highly ytterbium doped multimode core surrounded by high refractive index rods fiber exhibits a transverse singlemode behavior under continuous wave laser regime. A robust lp01 mode is observed and filtering effect is clearly observed. A non CVD process based on silica sand vitrification allows the synthesis of large and highly doped core with high index homogeneity, opening the way to design of efficient large mode area fiber lasers. 74% slope efficiency is measured, demonstrating the good quality of the core material. Finally, the use of rare earth (Er3+) doped zirconia nanocrystals in silica matrix offers a large panel of ignored energy transitions for visible or off-usual band of emission.","PeriodicalId":301956,"journal":{"name":"1st Workshop on Specialty Optical Fibers and Their Applications","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116489471","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}

These fibers have a number of unique features owing to their geometric structure, which consists of a matrix of regular holes that travels along its longitudinal axis. This design allows the selective insertion of materials such as gas and liquids, which interact efficiently with the guided modes. The insertion of materials can also be explored to introduce a new degree of freedom to control the properties of waveguide, by modifying modal features such as nonlinear coefficient and dispersion. Such control may, in some cases, contribute to increase the efficiency of nonlinear effects, enabling the creation of a supercontinumm spectrum. In this work we compare results obtained both experimentally and numerically of supercontinuum generation in a distilled water-core photonic crystal fiber. The results indicate the importance of setting the pump close to the zero dispersion region of the material so that a broad spectrum can be obtained. Improved agreement between experiments and simulations requires a better degree of experimental detail to be incorporated into the theoretical model, which will be the objective of future studies and work.","PeriodicalId":301956,"journal":{"name":"1st Workshop on Specialty Optical Fibers and Their Applications","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123471795","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 optical fiber consists of a photonic crystal fiber with hexagonal lattice of circular air-holes with an elliptical core formed by eight enlarged holes surrounding the central region of the fiber. Numerical analysis based on full-vector finite element method (VFEM) with a cylindrical perfectly matched layer (PML) was applied to evaluate the bending loss and the confinement loss of the fiber. For the straight fiber only the fundamental slow axis mode (x-polarization) exist because of the very high confinement loss of the fundamental fast axis mode (y-polarization). However, for the bent fiber the fast axis mode and the slow axis mode couple with the gallery of the cladding modes. These coupling prevent the fast axis mode to reach the cutoff. As a consequence, the bending loss curve as a function of the wavelength presents oscillations related with these coupled modes. Our simulations demonstrate that the analyzed fiber does not maintain its single-polarization single-mode characteristics when it is bent with a small curvature radius of 10 mm. However, for a small wavelength range (1.50 pm to 1.53 pm) the fundamental slow axis mode presents values of bending loss lower then 0.1 dB/km while the fast axis mode reach losses of about 150 dB/km, what can be useful for some application.","PeriodicalId":301956,"journal":{"name":"1st Workshop on Specialty Optical Fibers and Their Applications","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128326085","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 effect of each process variable was studied through a mathematical modeling and simulation of the methodology, comprising a simplified model of the soot deposition process. Results demonstrated that preforms with high elllipticity can be obtained by increasing the delay time or decreasing the maximum rotation velocity. It was also observed that the effect of the delay time is more noticeable on the preform geometry than the contribution of maximum velocity. These facts were confirmed when compared to real deposition results, using a VAD chamber with gases fluxes set to 2.33×10-6 m3/s (SiCl4) and 0.8×10-6 m3/s (GeCl4), and setting the burner-target angle to a high deposition rate condition. It is expected that the improvement of the mathematical model can be very useful in order to determine the process conditions necessary to achieve any desired preform geometry, even before the deposition stage.","PeriodicalId":301956,"journal":{"name":"1st Workshop on Specialty Optical Fibers and Their Applications","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127984605","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}
