Although optical networks are deployed to provide high bandwidth at reduced costs, they are not flexible and not efficiently utilized. Such applications require end-to-end delivery of information and flexible bandwidth allocation; therefore provisioning in optical networks need to be dynamic, flexible and consider provisioning in multiple domains. This paper presents a novel dynamic path computation algorithm for optical multi-domain networks. This algorithm updates the inter-domain paths and domainpsilas egress node dynamically after visiting an intermediate domain between the source and the destination. Simulation results show that the performance of the proposed algorithm is better than existing source routing algorithm for provisioning circuits in optical multi-domain networks.","PeriodicalId":298995,"journal":{"name":"2008 2nd ICTON Mediterranean Winter","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124645774","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 energy gap of BeSe is larger that that of ZnSe while the lattice constant of BeSe is lower than that of ZnSe. Both of them crystallize in sphalerite structure. By changing the content of beryllium it is possible to obtain material with different energy gap and lattice constant, matched to different substrates. For construction of optoelectronic devices the multilayer structures are commonly used. In such technology knowing of optical and thermal diffusivity of layer component materials is very important.

In this work we report a simple one step method for assembling spherical nanoparticles into wires without need for lithographic templating. It is effective for a variety of conducting and no conducting nanoparticles and substrates and the only material requirement is that the nanoparticles be placed in a colloidal suspension that is wettable on the desired substrate. The shape of the meniscus defines the wirepsilas geometry. We report the synthesis and physical properties of gold nanoparticles wires of several millimetres long and by a few micrometers wide.

Third-order frequency-dependent molecular polarizability gamma of the organometallics has been calculated using the Sum-Over-State (SOS) method. The origin of the non-linear optical properties of the investigated molecules is discussed within the semi-empirical ZINDO/1 approximation in frame of Restricted Hartree-Fock approach [2].
