当半导体量井(SQW ) 与激光交往时,低紧张的轻脉搏的组速度理论上被学习。由调整参数,慢点亮探查领域的繁殖,这被显示出能在如此的一个系统被展出。同时,探查吸收获得系列能从吸收被改变到零,即,电磁地导致的透明性(EIT ) 。试验性地观察轻繁殖是容易的,并且它在许多领域里导致潜在的应用固态量信息,例如光切换,察觉和量计算。
When semiconductor quantum wells(SQWs) interact with lasers,the group velocity of the low-intensity light pulse is studied theoretically.It is shown that by adjusting the parameters,slow light propagation of the probe field can be exhibited in such a system.Meanwhile,the probe absorption-gain spectra can be changed from absorption to zero,i.e.,electromagnetically induced transparency(EIT).It is easy to observe the light propagation experimentally,and it leads to potential applications in many fields of solid-state quantum information,for example,optical switching,detection and quantum computing.
