There are two kinds of Surface Plasmon resonances: lateral propagating Surface Plasmon waveguide modes excited by the diffraction of the grating which lead to dips in transmission; Surface Plasmon resonance between the slits of the grating, which leads to high extinction ration of TM to TE transmission. With simultaneous resonances, a compacted device of integrated color filter and polarizer can be achieved. In order to improve the transmission of TM light, an undercut structure is proposed. The mechanism of the enhancement is analyzed. Bi-layer metallic nanowire gratings are fabricated by laser interference lithography and subsequent E-beam deposition. The measured transmission and reflection spectra confirmed the theoretical and numerical simulations. The results will have wide potential applications in Displays, Optical communication, and integrated Optics.","PeriodicalId":179447,"journal":{"name":"SPIE/OSA/IEEE Asia Communications and Photonics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134334689","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 result shows the birefringence of the HB-PCF can be either increased or decreased significantly, depending on the connection conditions of the HB-PCF end, which are classified as case I (the end is closely butted by another fiber) and case II (the end is in open air). From the experiment and theoretical analysis, it has shown that in case I the retardation change of the spliced section of HB-PCF with 0.2mm in length can be 3.2 times larger than the original value. However, in case II the retardation may be reduced to 72.12% of the original one. The obtained result is important for the design and fabrication of optical fiber devices and sensors based on HB-PCFs.","PeriodicalId":179447,"journal":{"name":"SPIE/OSA/IEEE Asia Communications and Photonics","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132592135","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 novel Dual Routing Engine Architecture in Multi-layer and multi-domain Scalable and Constraint-Aware Policy-Enabled optical networks (DREAMSCAPE), exploiting the advantages of both GMPLS control plane and Path Computation Element (PCE), is introduced to improve the performance of routing in multi-layer and multi-domain optical networks in this paper. In the architecture, the cooperation of Group Engine (GE) and Unit Engine (UE) makes it effective to optimize path computation especially under complex multi-constraints. The functional architectures of dual routing engines are described in the paper. Based on this novel architecture, a testbed with more than 1000 GMPLS-based control nodes has been built in our lab using virtual machine technology, and two path computation approaches have been implemented on the testbed. The latest results are experimentally demonstrated on the testbed, and some future research issues are presented in the conclusion.","PeriodicalId":179447,"journal":{"name":"SPIE/OSA/IEEE Asia Communications and Photonics","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115819015","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}
