第九讲 光速减慢和光缓存技术

Slow light and all-optical buffers

高速光信号的存储是光信息科学的重要分支,全光缓存器是当今高速光信号处理的瓶颈.本文介绍了全光缓存器的研究进展,着重介绍了光速减慢的原理、物理基础,以及在半导体量子点中利用电磁诱导透明效应发展全光缓存器的思路.

The storage of optical signals with a high speed bit - rate is one of the most impotent fields of optical information technology, for which the all - optical buffer is the bottleneck. We review recent advances in the research of all - optical buffers, with emphasis on the principle of slow light and its physical bases. The development of an all - optical buffer using electromagnetically induced transparency in semiconductor quantum dots is discussed.
