Both a transmitter and a receiver are composed by two chaotic external-cavity semiconductor lasers which are coupled in a master-slave configuration to provide generalized synchronization, while the master lasers in the transmitter and in the receiver are completely synchronized via an optical fiber. A message is added to the slave laser in the transmitter and sent to the receiver to be compared with the output of the receiver slave laser. The system is robust to a small mismatch of the laser parameters or of the coupling between the master and slave lasers, unavoidable in a real system, and can even enable a good communication up to a 5 Gb/s transmission rate using the chaos masking encryption, when the master lasers in the transmitter and in the receiver are coupled bidirectionally.","PeriodicalId":173363,"journal":{"name":"2010 International Conference on Optical Communication Systems (OPTICS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116036445","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}

Excellent agreement between the actual probability density function (PDF) of each subcarrier and the Gaussian PDF estimated from a set of experimental runs is shown. The proposed EGA allows evaluate quickly the BER as only a few hundreds of runs are required to reach stabilized BER estimates. The BER estimated by EGA has shown an excellent agreement with the BER estimates provided by direct error counting.","PeriodicalId":173363,"journal":{"name":"2010 International Conference on Optical Communication Systems (OPTICS)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127016785","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 propose the use of a converged optical network adapted to the specific needs of the hospitality environment, providing a low-cost and low-power solution based on a combination of silica and plastic optical fiber wiring, together with radio-over-fiber techniques for wireless access. We use detailed full-system simulations to analyze the validity of such infrastructure to provide a unified, pervasive and future-proof all-optical solution.","PeriodicalId":173363,"journal":{"name":"2010 International Conference on Optical Communication Systems (OPTICS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123456229","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}

A digital camera was used to capture the Moiré images through an image processing to get the texture of each contour line. After calculated the texture of each contour line, the correspondence values are then filled. Each correspondence value will make smooth contour interpolation and then three-dimensional image of the object was plotted. This method for 3D measurement is simple and does not need an expensive measurement device to get precisely image information for a 3D rebuilt implementation.","PeriodicalId":173363,"journal":{"name":"2010 International Conference on Optical Communication Systems (OPTICS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114672404","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}
