Researches on photonic networks are very attractive because optical fibers have the inherent potentials of high-speed and wideband characteristics, low loss, resource saving, they are installed widely as information communications infrastructure, and multimedia networks require very high-speed/wideband transport systems. Important research objectives in this study are to realize ultra high-speed/large capacity transmission technology, high-density wavelength division multiplexing (WDM) technology and layered network architectures and quality.In future WDM-based photonic network, optical channel allocation is one of the important items. Frequency stabilization and tunable frequency light sources are indispensable for large capacity transmission, long distance transmission, and optical cross-connect. Basic model of light wave networks with stabilized light wave frequency supply module are investigated. The light wave supply module with pulsed sweep frequency generator is realized around … More 1,000 optical frequency timetables by improving its polarization sensitivity.The optical single sideband modulation (optical SSB) is investigated to overcome the effect of chromatic dispersion of the fiber. SSB modulation has such advantages as small bandwidth of a channel, low optical power of the SSB-SC (suppressed carrier SSB) format, and optical and electrical dispersion equalization capability. The novel property including high-density WDM capability was confirmed by simulation.Provisioning algorithm for survivable WDM optical path networks including routing and wavelength selection was studied for WP/VWP (wavelength path/virtual wavelength path) accommodation that can minimize the required number of wavelengths considering traffic demand and its distribution, network topology, and link failure scenario. The proposed heuristic algorithm shows the effectiveness for network planning. Wavelength conversion such as an optical frequency shifter over the path will become important in photonic GMPLS (Generalized Multi-Protocol Label Switching) router or MPA.S to create next generation networks. In summary, high density WDM networks with 10 times larger capacity will be feasible by the proposed system architecture and the transmission technology. Less

光子网络的研究非常有吸引力，因为光纤具有高速和宽带特性、低损耗、节省资源的固有潜力，它们作为信息通信基础设施被广泛安装，而多媒体网络需要非常高速/宽带的传输系统。本研究的重要研究目标是实现超高速/大容量传输技术、高密度波分复用(WDM)技术以及分层网络架构和质量。在未来基于WDM的光子网络中，光通道分配是重要项目之一。大容量传输、长距离传输、光交叉等都离不开稳频、可调频光源。研究了具有稳定光波频率供给模块的光波网络的基本模型。带有脉冲扫描频率发生器的光波供给模块通过提高其偏振灵敏度，实现了大约1000个光频率时间表。研究了光学单边带调制（光学SSB）以克服光纤色散的影响。 SSB调制具有通道带宽小、SSB-SC（抑制载波SSB）格式光功率低、光电色散均衡能力强等优点。通过仿真证实了包括高密度 WDM 能力在内的新颖特性。研究了可生存 WDM 光路网络的配置算法，包括路由和波长选择，以适应 WP/VWP（波长路径/虚拟波长路径），考虑到流量需求及其分布、网络拓扑和链路故障情况，可以最大限度地减少所需的波长数量。所提出的启发式算法显示了网络规划的有效性。波长转换（例如路径上的光学移频器）将在光子 GMPLS（通用多协议标签交换）路由器或 MPA.S 中变得非常重要，以创建下一代网络。总之，通过所提出的系统架构和传输技术，容量增加10倍的高密度WDM网络将是可行的。较少的
