摘　　要：近年来的研究表明,精确控制光脉冲在介质中的传播速度是完全可行的.利用电磁场与介质相互作用形成的电磁诱导透明,人们已在不同介质中实现了"超快"光和"慢"光效应的实验观测.其中,能使光脉冲的传播速度减慢甚至停滞的"慢"光效应,由于其在光信息存贮和光计算等领域的巨大潜在应用价值而引起了更多的关注,成为量子光学和非线性光学领域的研究热点.这里详细论述"慢"光形成的物理机制,并对相关理论及其实验研究过程进行分析.Recent research has established that it is possible to exercise extraordinary control of the velocity of propagation of light pulses through a material system. Both extremely slow propagation and fast propagation have been observed. Particularly, “Slow” light effect is of fundamental interest,and it hold promise for advances in practical areas from optical communication and devices to quantum computing. This article summarizes the recent research, placing special emphasis on the description of the underlying physical processes leading to the modification of the velocity of light..
