The inclination towards higher bit-rates and heterogeneous optical networks in the future challenges the popular assumption that chromatic dispersion (CD) is adequately compensated on a per-link basis. Recognising the importance of dispersion management, this paper proposes algorithms which apply metrics that contain dispersion information to both the routing and wavelength assignment sub-problems. To the best of our knowledge, this is the first attempt to include dispersion information within the wavelength assignment sub-problem. The newly proposed algorithm is named dispersion optimised impairment constraint-based RWA (DOIC). The performance is compared to existing routing and wavelength techniques under two scenarios: 40 Gb/s and mixed 10 Gb/s/40 Gb/s services. Two physical impairments under investigation are chromatic dispersion (CD) and optical signal to noise ratio (OSNR)","PeriodicalId":208725,"journal":{"name":"2006 International Conference on Transparent Optical Networks","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116032006","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}

Ideally this approach has the ability to route packets/bursts independently of bit rate, packet format and packet length. Still AOLS encounters new troubles. The lack of all-optical memory makes the AOLS nodes very complex and resource consuming. This is of great importance when providing the all-optical network with resilience. We focused on different protection/restoration schemes (real-time or in advance, local or end-to-end) that could be used in combination with all-optical packet-switching networks. We investigated how the presence of back-up facilities in the network affects the label length and number of labels needed throughout the network (i.e., the router's dimensions)","PeriodicalId":208725,"journal":{"name":"2006 International Conference on Transparent Optical Networks","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126103656","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 other words, optical routes can be taken partially to route demands creating a sort of \"lighttours\".

The difference can be explained by \"spinning\" during drawing of NZ-DSF fibres, leaving residual circular strain, which rotates radiation polarization plane, preventing accumulation of DGD in a fibre under axial and lateral pressure. Mechanical twist, e.g. due to stranding of fibres to make multi-fibre optical unit has the same effect.

While wanting to preserve the uni-directionality of the spiral, we also wanted to extract as much of the stored energy from the mu-disks at the expense of very high Q-value whispering gallery modes (WGMs). In this paper we present experimental results of directly coupling the flat edge of a spiral mu-cavity with the flat edge at one corner of a semicircle mu-cavity. The uni-directional emission appears normal to the flat edge of the opposite corner of a semicircle. The roles of the spiral as an oscillator and the semicircle as an amplifier are investigated with separate currents pumping the spiral and the semicircle. The competition between lasing modes (with narrow spectral peaks) and broadband amplified spontaneous emission (ASE) in the spiral for the inverted population in the semicircle limits the amplification process. The feedbacks provided by the Fresnel reflection on one side and the reflection from the channel on the coupled side cause the semicircle mu-disk to self oscillate above some current value. The directly coupled 2-element mu-disk provides an interesting system to explore as a means of achieving higher output power from mu-cavities","PeriodicalId":208725,"journal":{"name":"2006 International Conference on Transparent Optical Networks","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123420388","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}
