Coherent excitation is achieved by matching the repetition rate of a pumping mode-locked laser to a sub multiple of the free spectral range of one of the sets of modes of the disk. Once the disk is excited, we measure the resonatorpsilas quality factor by the fractional loss per round trip, and, after blocking the excitation, by the pulsed ringdown time decay. Both values agree with the quality factor measured by continuous wave transmission.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"59 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":"132507341","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 phase shifting algorithm always applies to reduce the additional noise within FD-OCT and provide accurate signal process. In this paper, we present a new system structure of group delay based phase shifting by combining diffraction grating pairs in frequency domain OCT. For the parallel grating pairpsilas property, we separate the spectrum and stretch the optical pulse in time to produce group delay result utilizing diffraction grating pair. It makes the linearly group delay between the different frequencies and provides accurate phase shifting algorithm, promotes the system performance and accuracy.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"5 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":"133340026","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 employment of metamaterials aims to overcome the intrinsic limitations of the standard components, based on the diffraction limit. In this way, patch antennas can be miniaturized compared to their traditional counterparts, leaky wave radiators can achieve improved directivity performances, resonant microwave absorbers can be miniaturized beyond 1/100 of the operating wavelength in terms of thickness, microstrip directional couplers can be made very short and with very high coupling values. The physical mechanisms behind the operation of such components, the analysis and design steps, and the experiments conducted in cooperation with other universities will be presented.

In this paper, integer lattice design based optical orthogonal code (OOC) has been discussed and analyzed for spectral amplitude coding schemes, applicable to both synchronous as well asynchronous incoherent OCDMA. Simplicity in code construction and flexibility in cross correlation control make this code a compelling candidate for future OCDMA applications. Signal to noise ratio (SNR) and bit error rate (BER) as a function of the number of users, code weight and userpsilas effective optical power have been analyzed for this code family. Further various parameters related to improvement of performance of BER have also been discussed in this paper.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"17 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":"132592700","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}

Optics provides greater bandwidths and long reach while wireless offers easier deployment, mobility and freedom to end users. By combining both, service experience is highly enhanced. Single types of transmission systems indeed have their advantages, but integration is essential if broadband really is for all. PON (passive optical networks) services together with UWB (ultra-wide band) generate advanced access solutions that once deployed, offer quadruple-play integration of wireless, voice, data and video applications.

Packets following a circuit are given absolute priority with no packet loss or jitter. Packets following a packet switched path are statistically multiplexed. Circuits are wavelength-paths in a Wavelength Routed Optical Network (WRON), resulting in bandwidth granularity of a wavelength. In this paper, we propose the HPTS scheme, enabling a higher granularity of the OpMiGua guaranteed service (GST) circuit paths by employing time-slots. Nodes sharing a wavelength path are allocated time-slots according to their bandwidth needs. Best effort traffic accesses unused bandwidth within any time-slot, enabling high bandwidth utilization. Finally, the proposed network schemepsilas compatibility with GMPLS is briefly discussed.","PeriodicalId":230802,"journal":{"name":"2008 10th Anniversary International Conference on Transparent Optical Networks","volume":"40 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":"114795024","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}
