Among them, one of the most attractive relies on slight modifications of existing and well behaving devices, i.e. by introducing a non-circular transverse layer section somewhere in the device. Even though experimental verifications. of this principle have already been carried out, a theoretical framework to better understand and possibly optimize such devices is still missing. This mainly originates from the need of a fully vectorial and three-dimensional approach. In this paper we will undertake a joint experimental and theoretical effort: first we give experimental evidence of polarization control by applying elliptical surface etching. Then, after having validated the vectorial electromagnetic model by comparing numerical and experimental results, we are able to better explain the polarization selection mechanisms and consequently to provide suggestions for optimized structures.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116665035","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}

Under the slowly varying envelope and paraxial approximation, we introduce a quite general approach to the analysis of the spatio-termporal dynamics of the coherent field beyond the mean-field limit, fully taking into account propagation, diffraction and the boundary conditions imposed by the cavity. We study the stability of the stationary solutions versus spatially modulated perturbations, and identify regimes where we observe total radiation confinement and the formation of 3D localised bright structures. At difference from freely propagating light bullets, here the self-organization proceeds from the combination of diffraction, nonlinearity and resonator feedback. Such cavity light bullets (CLBs) endlessly travel the cavity roundtrip and can be independently manipulated. These characteristics makes CLBs natural candidates for optical bits and for particle-like optical probes.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126288103","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 intelligent switching capabilities enable more dynamic networking, which may change the network characteristics significantly. The study of these changing characteristics is required in order to provide a firm basis for strategic network development decisions. After a brief overview of the ASON technology, the paper illustrates the potential advantages and drawbacks due to the dynamic behavior of the optical network. The analysis of numerical results from small network examples helps to highlight the main networking features of dynamic provisioning of optical channels. Based on the results of network simulations, a comparison of semi-permanent and switched connection based services is performed, taking into account different source activities. Finally, a quantitative analysis is given of the expected network resource savings originating from the statistical gains of automatic switching.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121247921","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}
