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.

The two techniques are based on two different paradigms. One is based on wavelength routing switching [1] and the other one on space routing switching [2]. Both techniques employ scalable and asynchronous label processor and label rewriter capable to process optical in-band labeling addresses. We demonstrate a 1times4 all-optical packet switch based on both techniques. We report for both technique experimental results showing the routing operation of the 160 Gb/s packets based on the processed in-band address information, and all-optical label erasing and new label insertion operation. Based on the experimental results, we discuss and compare both techniques in term of devices and bit-rate scalability, latency, power consumption, power penalty performance and cascadability as key parameters for the realization of an all-optical packet switching node.","PeriodicalId":298995,"journal":{"name":"2008 2nd ICTON Mediterranean Winter","volume":"158 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":"123365425","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 particular, metal nanoparticles have been widely applied due to their ease of synthesis, stability and potential for application ranging from magnetic memory to electronics and to catalysis. 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. As we demonstrate here, the technique is fast and easily controlled and can be used to make integrated nanoparticles wire arrays.","PeriodicalId":298995,"journal":{"name":"2008 2nd ICTON Mediterranean Winter","volume":"26 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":"126821454","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 investigated organometallics composites possess transition metals Ru and Cr and thatpsilas why investigation of their properties is very interesting with regard on metastable trapping levels originated from the d-states. Our interest is also focused on thiophene-based spacers such as oligothiophenes of various lengths and dithienylethylene. In this work we will determine the influence of these molecular structures on the improvement of their third-order NLO properties exploiting in particular the nature of the acceptor fragment and the pi-conjugated transmitter. 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]. Third order nonlinearities for the studied compounds were measured by degenerate four waves mixing (DFWM) experiment. The investigation of kinetics the third order nonlinear optical processes of organometallic embedded in polymethyl methacrylate (PMMA) and polyvinylcarbazole (PVK) polymer matrix will be introduced [3].
