中文摘要：

我们在两倍量点(QD ) 表明慢光在理论的回声分散材料。慢因素，吸收，和带宽被二个回声精力的精力差别极大地影响。这个系统的带宽直到 60 GHz。20 ps 输入信号脉搏被 180 ps (约 55 的组索引) 与很少为光通讯波长在 1 公里分散材料拓宽相对空间繁殖推迟。信号脉搏延期能被泵脉搏调节。

英文摘要：

We demonstrate the slow light in double quantum dots （QDs） resonance dispersion material in theory. The slow factor, absorption, and bandwidth are greatly influenced by the energy difference of the two resonance energy. The bandwidth of this system is up to 60 GHz. The 20 ps input signal pulse is delayed by 180 ps （group index of approximately 55） relative to free-space propagation with little broadening in 1 mm dispersion material for the optical communication wavelength. The signal pulse delay can be tuned by the pump pulse.
