The technique utilizes the fact that the spectral interference fringes are resolved at the output of a tandem configuration of the compensated (non-dispersive) Michelson interferometer and a two-mode optical fiber only in the vicinities of so-called equalization wavelengths at which the optical path difference (OPD) in the interferometer is the same as the intermodal group OPDs. The white-light spectral interferometric technique is used to measure the spectral dependences of both the differences between propagation constants of modes and the intermodal group OPD for elliptical-core (highly birefringent) optical fibers. The measured dispersion characteristics of the optical fibers are compared with those corresponding to the results of an adequate theoretical analysis using the known parameters of the optical fibers.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"17 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":"115432492","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}

PC technology will make possible applications such as compact filters, sharply bent waveguides or highly efficient light emitting devices. The fabrication of these devices can be possible if enough dielectric contrast is achieved in the spectral region of interest. Among the available materials for photonic applications, organic compounds, both small molecules and polymers, have attracted in the last few years an increasing interest, due to their low cost, easy functionalization and possibility to finely tune their optical and electrical properties. In spite of their strong potential, these organic materials typically show a low refractive index contrast, which makes it difficult a complete photonic band gap to be obtained. Furthermore, most organic material cannot be exposed to high-energy electrons during e-beam lithography, or cannot be processed by standard lithographic wet solutions. We present an overview of the materials and nanotechnological processes necessary for the fabrication of 1D and 2D hybrid organic/inorganic photonic crystals devices. Passive and active devices with different device geometries as well as novel fabrication approaches will be presented and discussed.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"2 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":"128050513","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 this paper, optical layer networking using MEMS-based optical switches both for ring and mesh networks is discussed. Fast protection time of about 20 ms for IP layer has been achieved by the optical layer protection with the optical network protection equipment using a 2D-MEMS in a 500 km bidirectional wavelength path switching ring network. The obtained switching time was comparable to that of optical cross connect using electrical switching fabrics. Regarding the intelligent optical network using the generalized multi-protocol label switching (GMPLS) protocols, interworking between a photonic cross connect based on a 3D-MEMS and an IP/MPLS router has been confirmed. Fast wavelength path provisioning as well as proper path restoration has been also achieved with the GMPLS testbed including three photonic cross connect nodes and 1000 km bidirectional transmission line. Finally, the feasibility of the transparent all-optical network has been demonstrated with the GMPLS testbed.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"9 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":"124857769","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}

Three deployment stages are described; starting from the current quasi-static networks a migration to faster optical switching technology will be made plausible when these components become cost effective. The initial phase requires a carefully balanced engineering between the optical and electronic layers to avoid large inefficiencies and could be done introducing short duration slots with packet aggregation in larger frames/super packets under the control of an appropriate MAC protocol. The latter two phases delegate higher functionality to the optical layer allowing advanced statistical multiplexing within it.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"69 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":"130411086","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}

Mathematical modeling of lasing in semiconductor microcavities by means of adequate eigenvalue problems 利用充分本征值问题建立半导体微腔激光的数学模型

In facts thresholdless lasing idea had appeared when it was noticed that infinite photonic crystals display frequency bandgaps, in which no electromagnetic wave can propagate. Therefore, it was suggested that a microcrystal or defect-cavity laser in a photonic crystal host medium might have zero threshold. However, no crystal is infinite, therefore the thresholds can be only made small. In fact, zero threshold is completely equivalent to zero output light. Therefore it appears that analyses of lasing in infinite photonic crystals are either erroneous, if done approximately or with coarse numerical methods like FDTD, or has no sense at all, if done with accurate methods, which correctly account for the radiation conditions. Instead, one must simply formulate the LEP with a finite-size photonic-crystal encasing a laser resonator and study the reduction of the thresholds as a function of elementary cell size, topology, filling, and number.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"20 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":"132398695","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}
