Strong confinement and controlled feedback are also important for efficient and compact sources for light with various levels of coherence and directionality. The presentation will survey work on various planar photonic crystal and wire device structures realised both in material systems providing strong vertical confinement (e.g. S-o-I) and in systems with weak vertical confinement such as typical epitaxial III-V semiconductor heterostructures. Work towards the combination of a number of elements into a single photonic IC will be highlighted, as will structures which combine photonic crystal and photonic wire features. Planar microcavities for frequency selection will be featured, in particular. We shall also resurvey briefly the technology aspects of fabrication, including electron-beam lithography (EBL), reactive ion etching (RIE), focused ion-beam etching (FIBS) and excimer laser lithography. Finally we shall consider techniques for the growth of self-organised photonic crystals with greater perfection and better controlled orientation.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"510 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123424599","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 signal is directly modulated onto three high-speed lasers with emission frequencies spaced by 50 GHz. Bragg filters are employed at the receiver base station in order both to demultiplex the required optical channel, and to ensure that the detected signal is single side band (in order to overcome dispersion limitations on the link). Our results show negligible degradation in system performance for the demultiplexing of the WDM signal compared with the back-to-back performance curves.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130184861","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 presented optically transparent network represent a novel approach in fiber-to-the-desk applications. It is made to minimize the costs associated with a passive optical LAN implementation. The biggest issues in the realization of the network are the synchronization of bursty traffic and collision detection. We present, in detail, the solution to the synchronization problem by introducing an analog sinusoidal carrier that is in addition to the data signal only sent within the data packet duration. The extraction of data and the synchronization signal is made by using simple filtering, facilitating the receiver realization.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132079503","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}

Delayed redistribution of intensity over the beam cross-section due to nonlinear self-focusing and self-phase-modulation effects is shown to affect the phase and the amplitude dynamics of the output signal in a rather nontrivial way, depending on the carrier laser frequency.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133141805","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}

Towards a dynamic hierarchical cross-connecting without wavelength conversion in multi-fiber WDM networks 多光纤WDM网络中无波长转换的动态分层交叉连接

The HXCs implement an optical bypass, at coarse granularity using the wavelength banding technique with waveband cross-connects (WBXC), and, at fine granularity, using wavelength cross-connects (WXC). Reducing the possibility of fine granularity switching results in reducing the OXC complexity at the expense of increasing the blocking probability. In particular, we do not allow the use of wavelength converters in order to reduce the global cost further. Two parameters, /spl mu/ and /spl beta/, define the optical node architecture with a calculated complexity reduction ratio and a simulated blocking probability. Fixing a maximum blocking probability and a minimum complexity reduction results in choosing /spl mu/ and /spl beta/, and hence the node design, for a maximum given traffic load.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133300584","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}

However, the gain bandwidth of usual fiber amplifiers is limited to a maximum of 80 nm in the C- and L-band. Todays optical senders and receivers are limited to a spectral efficiency of not more than 1 bit/s/Hz which results in a total capacity of about 10 Tbit/s in the C- and L-bands. Meanwhile the crash of the telecom market damped the bandwidth growth somewhat, but it is still an important task to work on solutions for transmission systems at extremely high bitrates beyond 10 Tbit/s. One of these solutions is the use of larger parts of the low attenuation window of the transmission fibers. It seems to be consensus that the first step towards this direction will be the S- and S/sup +/-band at 1450-1530 nm. Here we will give an overview of the current status and new developments in the field of S-band fiber amplifier technologies. As usual, the term S-band will be used for Sand S/sup +/-band in this work.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123915454","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}
