The temperature distribution on the fiber cross-section is calculated with an analytical model, for different pump power values. The consequent refractive index change, due to the thermo-optical effect, is applied to the cross-section of the DMF fiber, whose guiding properties are studied with a full-vector modal solver based on the finite element method. A DMF fiber design, which is single-mode in the 1030 nm-1064 nm region, is considered, and the effects of thermal load on the transmission characteristics are evaluated. Results show a blue-shift of the single-mode window and the single-mode bandwidth narrowing as the absorbed pump power becomes higher.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129237675","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 spectrum rearrangement consists in changing the spectral order of wavebands (group of frequency slots that must remain contiguous) while keeping the same distribution plan as specified by routing and spectrum assignment. The goal of spectrum rearrangement is to reduce spectral fragmentation and to maximize the bandwidth freedom to provision new lightpaths by privileging the contiguity of unused frequency slots, i.e. filling spectrum voids. Rearrangement in the described concept was first introduced by the authors for a wavelength-routed network to enhance the performance of a hierarchical structure of waveband granularities. In this paper, wavelength rearrangement is revisited all along with the newly introduced spectrum rearrangement in order to highlight on the benefit of approaching the problem from a global network view.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131117009","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}

This constitutes the basis of chemistry. Similar effects appear in neighboring optical microcavities when shined with a laser beam. Following this analogy, the optical modes of a microcavity resemble to the electronic orbitals of an atom, then called photonic atom (PA). The photonic interaction of several PAs may form photonic molecules (PM). The PM concept, has allowed studying new properties of light-matter interaction. Also it has been applied to realize low threshold microlasers, enhanced directional light emission, high sensitivity sensors and even quantum information processes. The most typical examples of PAs range metallic nanoparticles, to low refractive index dielectric microspheres or microdisks. In the former case (metallic PAs), the high optical dissipation of metals is a big obstacle for developing devices. In the case of low refractive index PAs the whispering gallery modes (WGM) contributing to photonic binding are always localized at the cavity surface, so they would be equivalent to atoms excited into high-energy orbitals. Furthermore, as it happens for electronic orbitals, the electrical resonances of photonic PAs and PMs play a dominant role over the magnetic ones. Here, we show our recent experimental and theoretical results concerning: A) The optical properties of spherical nanocavities made of silicon in the submicron range. B) The strong interaction between silicon colloidal and its mirror image under perfect electric conductor.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127262917","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}

Their low internal losses make QD based devices suitable for high-speed telecommunication applications. Increase of data transmission rate by wavelength division multiplexing techniques requires temperature stable longitudinal single-mode transmitters. We present 1.3 μm index-coupled QD distributed feedback (DFB) lasers with p-doped active region showing wide temperature independent operation, high side-mode suppression ratio (>; 55 dB) and quantum efficiencies up to 40%. The data rate achieved by direct modulation is exceeded by using QD electro-absorption modulators (EAMs) based on the Quantum-Confined Stark Effect. Presently we achieve a 3 dB-bandwidth of 17 GHz and extinction ratios of 18 dB. Monolithic integration of both, DFB and EAM, into a single two-section device provides an inexpensive transmitter unit suitable for metropolitan area network applications.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126977852","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}
