The exhibit hall grew by 20 percent over last year, featuring new programming for service providers and data center operators, and more exhibitors filling a larger space, alongside its core show floor programs and activities. The more than 500 companies in the exhibition hall showcased innovations in areas such as 100G, tunable XFPs, metro networking, Photonic Integrated Circuits, and more. On hand to demonstrate where the industry is headed were network and test equipment vendors, sub-system and component manufacturers, as well as software, fiber cable and specialty fiber manufacturers. Service providers and enterprises were there to get the latest information on building or upgrading networks or datacenters. OFC/NFOEC also featured expanded program offerings in the areas of high-speed data communications, optical internetworking, wireless backhaul and supercomputing for its 2011 conference and exhibition. This new content and more was featured in standing-room only programs such as the Optical Business Forum, Ethernet Alliance Program, Optical Internetworking Forum Program, Green Touch Panel Session, a special symposium on Meeting the Computercom Challenge and more. Flagship programs Market Watch and the Service Provider Summit also featured topics on data centers, wireless, 100G, and optical networking. Hundreds of educational workshops, short courses, tutorial sessions and invited talks at OFC/NFOEC covered hot topics such as datacom, FTTx/in-home, wireless backhaul, next generation data transfer technology, 100G, coherent, and photonic integration.

With more than 1,500 talks on the latest breakthroughs in research and applications, these conferences are the source of the most timely and innovative new developments for the industry. Consistent with previous year's shows, attendance reached 5,200. Technical attendance was strong at more than 2,500 and exhibit walk-in traffic remained steady with 2005. The CLEO exhibition showcased 358 participating companies this year, with almost a 100 percent increase in corporate sponsor participation. The show really is an international must- attend event, with approximately 25% of companies coming from outside the United States. There also were exciting new programs and topics introduced at the 2006 event. The PhAST conference established the PhAST/Laser Focus World Innovation Award which recognizes a company who has developed one of the most promising new products in the field. This year, Daylight Solutions won for its submission, "Commercializing the Mid-IR" and four honorable mentions were given to Thorlabs, Sacher Lasertechnik, Fianium and PolarOnyx. CLEO also launched the Terahertz Technologies and Applications subcommittee, a new topic area developed due to a consistent increase in papers in this area over the last few meetings. CLEO/QELS and PhAST had a great year in 2006. We're looking forward to seeing you in Baltimore , May 6-11, 2007. Conference Program Postdeadline Papers CPDA-CLEO Postdeadline Session I CPDA1 St.

  • Control Plane Routing in Photonic Networks
    Control plane routing in photonic networks Robert John Friskney A thesis submitted to University College London for the degree of Doctor in Engineering (Eng.D). Communications Engineering Doctorate Centre Department of Electronic and Electrical Engineering University College London August 2011 Declaration I, Robert John Friskney, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Signed: Date: Abstract The work described in the thesis investigates the features of control plane functionality for routing wavelength paths to serve a set of sub-wavelength demands. The work takes account of routing problems only found in physical network layers, notably analogue transmission impairments. Much work exists on routing connections for dynamic Wavelength-Routed Optical Networks (WRON) and to demonstrate their advantages over static photonic networks. However, the question of how agile the WRON should be has not been addressed quantitatively. A categorization of switching speeds is extended, and compared with the reasons for requiring network agility. The increase of effective network capacity achieved with increased agility is quantified through new simulations. It is demonstrated that this benefit only occurs within a certain window of network fill; achievement of significant gain from a more-agile network may be prevented by the operator’s chosen tolerable blocking probability. The Wavelength Path Sharing (WPS) scheme uses semi-static wavelengths to form unidirectional photonic shared buses, reducing the need for photonic agility. Making WPS more practical, novel improved routing algorithms are proposed and evaluated for both execution time and performance, offering significant benefit in speed at modest cost in efficiency.

Land Smith 2021 MELS ii Abstract Sina Queyras, in the essay “Lyric Conceptualism: A Manifesto in Progress,” describes the Lyric Conceptualist as a poet capable of recognizing the effects of disparate movements and employing a variety of lyric, conceptual, and language poetry techniques to continue to innovate in poetry without dismissing the work of other schools of poetic thought. Queyras sees the lyric conceptualist as an artistic curator who collects, modifies, selects, synthesizes, and adapts, to create verse that is both conceptual and accessible, using relevant materials and techniques from the past and present. This dissertation responds to Queyras’s idea with a collection of original poems in the lyric conceptualist mode, supported by a critical exegesis of that work.

MCFs generally have homogeneous multicore fibers with weakly coupled cores. It is experimentally shown that the crosstalk-induced SNR penalty is multiple cores within a shared cladding. The cores have similar independent of the transmission distance on sufficiently long uni- propagation characteristics, which enables the transmission of form links. This results from the approximately linear scaling of time-aligned spatial super channels over long distances [1]. As the noise contributions from amplified spontaneous emission, fiber a consequence, it becomes possible to use shared transmission nonlinearity, and crosstalk with the transmission distance. The hardware, digital signal processing (DSP) resources [6], and crosstalk-induced SNR penalty on C and L band WDM long dis- tance links is experimentally evaluated, showing significant degra- spatial dimension-based modulation and/or coding [7].
