| 摘 要： | 从空间和时间相互耦合的３＋１维波动方程出发，讨论了光场在线性介质中的传输特性。在理论上发现：即使存在群色散效应，也可以实现光脉冲的无畸变传输。文中给出了实现无畸变传输的条件并讨论了光场在正常色散区域及反常色散区域的传输特性

| Abstract: | The properties of optical pulses in bulk linear media are studied for the wave equation of three spatial and one temporal dimensions in this paper. The results show that it is possible to realize the transmission of optical pulses without distortion even though there exists effect of group-velocity dispersion. The conditions of transmission are also given. Finally, the properties of transmission are discussed in detail in normal and anomalous dispersive regions. |
