Many routing and wavelength assignment (RWA) algorithms, proposed for lightpath provisioning, base their routing decisions on the availability of network resources, and assume that optical fibers and components are ideal. In reality, physical impairments degrade the quality of the optical signal propagating through fiber segments and optical components. To cope with this problem, Impairment Constraint Based Routing (ICBR) algorithms, that consider physical impairments during connection provisioning, are currently proposed to prevent selecting lightpaths with poor signal quality. However, these algorithms support only a single (highest) quality of transmission threshold, the same one for all connection requests. This does not fit well with the variety of services, with potentially disparate QoS requirements, that the next generation networks are expected to support. Consequently, the efficiency of network resource utilization is reduced. This paper demonstrates that a significant improvement, in terms of blocking probability, can be achieved when using an ICBR algorithm with differentiated physical layer constraints. Performance is compared with conventional impairment aware routing approaches when unprotected, shared path protected (SPP), and dedicated path protected (DPP) connection requests are considered. The achieved improvement is a result of more efficient resource utilization as unnecessary connection blocking can be avoided by selecting network resources offering optical signal quality that is “good enough”good enough to satisfy a specific connection request. to satisfy a specific connection request.","PeriodicalId":366119,"journal":{"name":"2009 Asia Communications and Photonics conference and Exhibition (ACP)","volume":"69 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132418220","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 continuous-wave (CW) output power of single QD-VCSEL of 1.2 mW with lasing wavelength of 1.28 µm is obtained at room temperature (RT) at a bias current of 15 mA without power saturation. The low threshold current of 1.1 mA can be achieved for the single mode device. We investigate the 3-dB modulation bandwidth of QD-VCSELs with oxide aperture size of 5-µm, 10-µm and 15-µm in the small signal frequency response measurements. Modulation bandwidth of 2.65 GHz is achieved for single-mode QD-VCSEL with oxide aperture size of 5 µm at a bias current of 4.5 mA. The maximum modulation bandwidth of 2.5 GHz can be obtained for multimode QD-VCSEL with oxide aperture size of 10 µm at a bias current of 7 mA. The 61 QD-VCSELs array is also investigated at RT without optimization. Maximum CW output power of 28 mW and pulsed output power of 18 mW are demonstrated for 2-D QD-VCSEL array with threshold current of 50 mA. The far field pattern beam angle of QD-VCSEL arrays at two perpendicular directions are about 18 degree.","PeriodicalId":366119,"journal":{"name":"2009 Asia Communications and Photonics conference and Exhibition (ACP)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132041976","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}
