Numerous modulation schemes have been studied in this area. Multiple pulse position modulation (MPPM) has proved to be more power efficient than other modulation schemes such as on off keying (OOK), pulse amplitude modulation (PAM), and pulse position modulation (PPM). However, MPPM is not a strong candidate when the bandwidth efficiency is taken into account. To achieve optimum power and bandwidth efficiency, a new modulation scheme, multiple pulse amplitude and position modulation (MPAPM), is proposed. This paper analyses the proposed modulation scheme in terms of bandwidth requirements and power efficiency. The new scheme delivers an improvement in energy per unit bandwidth of 10 dB.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115775661","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}

We present a 1times4 all-optical packet switch based on label swapping technique that utilizes a scalable and asynchronous label processor and label rewriter. The packet address information is encoded by in-band labels. With this we mean that the wavelengths of the labels are chosen within the bandwidth of the payload. We encode addresses by combining different labels. Thus, by using N in-band label wavelengths, 2N possible addresses can be encoded, which makes this labelling technique highly scalable within a limited bandwidth. Experimental results showed error-free packet switching operation at 160 Gb/s, while the label erasing and new label insertion operation introduces only 0.5 dB of power penalty. Those results indicate a potential utilization of the presented technique in a multi-hops packet switched network.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114856103","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}

To this end, we firstly identify major protocol disruptions due to connectivity outages in the control plane. This allows the derivation of a new parameter, which quantifies such disruptions thus providing a figure of merit for performance evaluation. As the main contribution, we propose and validate different control plane topologies over a meshed transport network scenario. In particular, through simulation results, we initially provide comparison amongst them from a resilience viewpoint. Secondly, we focus on certain network resilience requirements and we discuss the suitability of either IP rerouting or dedicated backup control link protection as the failure recovery mechanism.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127923878","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 future packet-switching networks, it is feared that a large intensity variance of optical signals in optical packets would be caused by such a clock recovery, and a gain transient of EDFA, and so on. To cope with the large intensity variance of optical signals in optical packets, we propose a wide dynamic range all-optical intensity equalizer based on an effective control of spectral modulation induced by self-phase modulation (SPM) using super-Gaussian signals. We have calculated the spectra after SPM effects for super-Gaussian signals with changing the intensities of input optical signals. As the results, we have successfully realized appropriate control of spectral modulation so that the magnitudes around centre wavelength components might be approximately equivalent for input intensities over a wide range. By using computer simulation, we have verified the function of proposed intensity equalizer by adopting the calculated magnitude-equivalence after SPM. We confirmed a remarkable wide dynamic range and a high-accuracy intensity equalizing effect of the proposed method.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114966992","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, semiconductor nanocrystals are widely exploited as quantum optical emitters, showing very high quantum yield (close to unity), stability, low tendency to photobleaching and possibility to be tuned from ultraviolet to infrared range. The realization of high performing photonic devices based on this class of emitters is therefore an extremely intriguing challenge; on the other hand, the best way to manipulate these emitters and integrate them in solid matrices, without dramatically decreasing their optical properties, is still under debate. Here we present a method for the fabrication of the main building blocks of photonic circuits by exploiting the localization of colloidal nanocrystals dispersed in polymeric matrices through lithographic techniques. The realization of waveguide structures, suspended stripes and photonic crystal nanocavities is shown as a demonstration of this approach.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121114351","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}
