It is found that the transfer matrix between rings n, n + 2, n + 4 , ... is independent of the polygon vertex angle, allowing the application of Floquet theorem for periodic propagation in a cylindrically symmetric structure. Corresponding to even or odd N, the molecule possesses 1 + N/2 or 1 + N discrete resonances, which satisfy the dispersion equation of the straight coupled-resonator optical waveguide (CROW) with infinite rings. The field amplitudes in the rings are determined as eigenvectors of the corresponding eigenvalue problem. By incorporating the molecule into a channel dropping filter system, the presence of these resonances in the transmission spectrum is verified.","PeriodicalId":265478,"journal":{"name":"2007 9th International Conference on Transparent Optical Networks","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122774856","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}

There are two reasons for that. As silicon is an indirect band gap semiconductor, achieving light emission and gain is quite difficult. On the other hand, for using silicon as a light guiding material for passive devices, the main constrains until recently were relatively high propagation losses and high fiber-to-waveguide incoupling losses. The general trend towards more compact photonic devices together with progress in fabrication techniques resulted in the development of two nano-photonic technologies for next generation optical devices: photonic crystals and nanowire waveguides-based devices. To drastically increase the integration density and achieve subwavelength confinement of light along the propagation direction, plasmonic waveguides have been proposed. Surface plasmons are electromagnetic modes constituted on the interface between a metal and a dielectric. The tradeoff between the light confinement and propagation loss has here a vital importance.","PeriodicalId":265478,"journal":{"name":"2007 9th International Conference on Transparent Optical Networks","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122027928","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}

Mohan Saxena","doi":"10.1109/ICTON.2007.4296048","DOIUrl":"https://doi.org/10.1109/ICTON.2007.4296048","url":null,"abstract":"OCDMA is a highly flexible technique to achieve high-speed connectivity with large bandwidth. Data access security and ability to support asynchronous, bursty data transmission are two of the main driving forces behind a lot of interest in the OCDMA techniques. On the other hand, the poor spectral efficiency of OCDMA systems demand appropriate choice of coding techniques and multi-access interference (MAI) is often a limiting factor. This paper describes a simulated model for an incoherent Gigabit OCDMA system using high performance W/T codes. 60 km fiber amplifier span has been used in this model. Earlier work has been done at 1.25 Gbps for 16 users. In this paper OCDMA system beyond 1.25 Gbps is suggested by redesigning W/T code using 8-wavelength and 8-time slots. By using modified W/T code the MAI reduces. The analysis takes into account the effect of data rates for increasing number of simultaneous users and received power. The system performance is evaluated by eye diagram and BER analysis at different data rates. The system has been designed for 1 Gbps, 1.25 Gbps, 2.5 Gbps and 5 Gbps. BER analysis for asynchronous concurrent communication of multiple users at different data rates has been done. Results show that the Bit-Error-Rate performance for 1.25 Gbps improves in comparison to previous designs. The designed system provides adequate BER (<10-9) for 2.5 Gbps up to 16 users and for 5 Gbps up to 8 users.","PeriodicalId":265478,"journal":{"name":"2007 9th International Conference on Transparent Optical Networks","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128607142","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 cost function is referred to as \"step function\" or \"staged capacity cost\". If a sequential algorithm is used to design the networks it often results in sub-optimal solution due to the so called \"long path problem\", where the weighted shortest path algorithms rather choose very long paths where such links are chosen where no additional capacity step (and therefore no additional cost step) has to be made. In this paper we propose and compare methods that perform randomised smoothing of these staged capacity cost functions to allow decomposition of the network design problem to a sequence of weighted shortest path searches, that is the mostly used approach. The problem can be interpreted as an Unsplittable Multi-Commodity Flow Problem with staged capacity costs.","PeriodicalId":265478,"journal":{"name":"2007 9th International Conference on Transparent Optical Networks","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129055687","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}
