全光开关系统接近实际应用由于缺少光开关系统，现实世界中一直未能使用全光通讯网络。包括使用甚窄光谱宽度半导体激光器和掺饵光纤放大器的单馍色散移动光纤在内的所有其它必要元件均已有了。这种网络实际能以无限速度工作。正在发展用于通讯系统的自由空间光子开关技术... All-optical switching system is close to the practical application Due to the lack of optical switching system, the whole world has been unable to use all-optical communication network. All other necessary components including a single-fiber dispersion-shifted fiber using very narrow spectral width semiconductor lasers and erbium-doped fiber amplifiers are available. This kind of network can actually work with unlimited speed. Developing free-space photonic switch technology for communication systems ...
