研究了VCSEL的饱和效应对激光器的慢光延时的影响，推导出相位和延时的关系。(The influence of saturation effect of VCSEL on the slow light delay of laser is studied, and the relation between phase and delay is deduced.)

基于VSEL慢光的传输延时的限制方针和实验，表明VSEL器件收到饱和等因素的影响，延时时间收到限制。(The delay policy and experiment of slow light transmission based on VSEL show that the VSEL device receives saturation and other factors, and the delay time is limited.)
