In this paper, we experimentally observed a 35nm type-I QPM SFG bandwidth in MgO:PPLN, and energy competition between SFG and SHG has been demonstrated firstly. Based on simultaneous cSFG/DFG and cSHG/DFG, a novel multi-broadcast wavelength conversion scheme is proposed, which has the advantage of broadcasting one signal to multiple idlers. © 2009 OSA/ACP.

We propose a 40Gbit/s star-16QAM(to define) system based on ISI(to define)-suppression technology and coherent detection. ISI-free BPSK optical signals generated by Mach-Zehnder modulators (MZM) and continuous wave (CW) lights are used to realize a star-16QAM signal. As a result, the obtained star-16QAM signal is also ISI-free. It turns out that the proposed ISI free star-16QAM has better performance in terms of eye opening and constellation diagram comparing with two conventional star-16QAM signals transmitted through 80-km standard single-mode fiber (SSMF) and detected by a coherent receiver. © 2009 Copyright SPIE - The International Society for optical Engineering.

We propose a novel scheme to achieve a tunable multiple wavelength conversion in an AOS waveguide structure. The full spectrum of input 1.57ps pulsed signals at 40Gbit/s can be converted to outputs at a relative-high and equalizing efficiency, which ensures high-bit-rate N*M broadcast wavelength conversion without pulse broadening and distortion. ©2009 optical Society of America.

We experimentally demonstrate wavelength multicasting based on free carrier dispersion effect in a silicon mode-split microring resonator with a radius of ∼10 μm. The mode-split of the resonator is caused by mutual coupling between the co-propagating and counter-propagating modes inside the microring resonator, which is induced by the periodic grating-like roughness of the sidewalls. The free carriers are generated through the two photon absorption (TPA) effect and blue shift the resonance spectrum. 1.25-Gb/s data carried by the pump is simultaneously converted to two probe channels placed in the split resonances separated by ∼0.326 nm. ©2009 IEEE.

We propose a novel scheme to overlay multicast service over a wavelength-division-multiplexed (WDM) passive optical network (PON) based on dynamic wavelength reflection scheme. At the optical line terminal (OLT), for each WDM channel, a dynamic wavelength reflector is used to selectively bypass the corresponding optical carrier to avoid multicast data superimposition, while the remaining optical carriers go through the dynamic wavelength reflector and simultaneously carry the multicast data. The proposed scheme is experimentally demonstrated with 5-Gb/s downstream unicast, multicast data and 625-Mb/s upstream re-modulated data. © 2009 SPIE-OSA-IEEE.

Dynamic bandwidth allocation for supporting dynamic service level agreements in EPON

Journal of optical commun.cations 2008年第4期29卷 232-238页

Recently, Ethernet Passive optical networks (EPON) is being deployed widely as the next generation broadband access networks due to the convergence of low cost Ethernet equipment and low cost fiber infrastructure. Because of the use of shared transmission media between all users, an efficient dynamic bandwidth allocation (DBA) is necessary to enable the quality of service (QoS) in EPON. However, to receive guaranteed QoS, end users first have to sign the contract called Service Level Agreement (SLA) with service provider in which specifies the QoS performances of the provider has to promise as well as the obligations the end users have to obey. Therefore, the central issue of QoS support in EPON is the appropriate dynamic bandwidth allocation scheme that makes sure the SLAs can be exactly fulfilled. According to the negotiation fashions, the SLA can be static or dynamic. Based on current standardized EPON architecture, most studies of the DBA schemes have only focused on achieving static SLAs, and the DBA for dynamic SLAs is rarely discussed. This paper firstly addresses this issue with an extension of EPON framework that supports dynamic SLAs negotiation, and further proposes a dynamic bandwidth allocation (DBA) scheme to fulfill the dynamic SLAs. Detailed simulation experiments are also conducted to study the performance and validate the effectiveness of the proposed solution.

In this paper,the sharing schemes of multicast in survivable Wavelength-Division Multi-plexed(WDM) networks are studied and the concept of Shared Risk Link Group(SRLG) is *** the network resources are shared by the backup paths,the sharing way is possible to make the backup paths *** selfishness leads the redundant hops of the backup route and a large number of primary lightpaths to share one backup *** sharing schemes,especially,the self-sharing and cross-sharing,are investigated to avoid the selfishness when computing the backup *** order to decrease the selfishness of the backup paths,it is important to make the sharing links fair to be *** is a trade-off between the self-sharing and cross-sharing,which is adjusted through simulation to adapt the sharing degree of each sharing scheme and save the network resources.
