| 摘 要： | 全光通信一直是光通信领域的一个追求,其中最大的瓶颈来源于过去光电转换的不可或缺。近些年来,随着量子干涉与量子信息技术的发展,人们已经实现了对于光脉冲实施群速度的任意操控,乃至于将光脉冲相干地存储在介质中,然后释放出来。这为最终真正地实现可以实用的光存储,并最终实现全光通信带来了极大的希望。

| Abstract: | All-optical communication is a pursuance in optical communications, which has not yet been realized owing to that the electric-optic conversion can not be avoided in current technologies. In recent years, thanks to the development in quantum coherence and quantum information technologies, people have implemented the coherent manipulation of the group velocity of the light pulse. Moreover, one has achieved the short time storage of light pulse in medium and then releases it. These achievements have shown brilliant future to the final implementation of applicable light storage and therefore the all-optical communications. |
