| 摘 要： | 文章介绍了作者利用光波位相耦合的色散效应调控光速的新机制，并利用光折变位相耦合的色散效应在室温下在Bi12SO20晶体中实现极慢光速和超光速现象．进一步的研究表明，在Bi12SO20晶体中传播的、由位相耦合色散效应引起的慢光和快光由于光折变光强耦合效应而得到了相干放大．

| Abstract: | A new mechanism to control the group velocity of light based on the dispersive effect of phase coupling has been developed, by means of which we have realized uhraslow and superluminal light propagation in photorefractive Bi12SiO20 crystal at room temperature through the photorefractive phase coupling effect. The uhraslow and superluminal light were shown to be amplified due to photorefractive intensity coupling in the crystal. |
