具有自诱导透明的光学前驱体

Optical Precursors with Self-induced Transparency

Bruno Macke, Bernard Ségard

摘要:

最近已经在具有电磁感应透明窗口的不透明介质中观察到显著领先于具有可比幅度的主场的光学索默-布里渊前体[Wei等人,物理修订版信函103,093602(2009)]。本文从理论上分析了由传播场本身引起透明时所得到的类似结果,并建立了主场到达时间延迟的近似解析表达式,它与数值求解Maxwell-Bloch方程所得到的结果相当吻合。

英文摘要:

Optical Sommerfeld-Brillouin precursors significantly ahead of a main field of comparable amplitude have been recently observed in an opaque medium with an electromagnetically induced transparency window [Wei et al., Phys. Rev. Lett. 103, 093602 (2009)]. We theoretically analyze in this paper the somewhat similar results obtained when the transparency is induced by the propagating field itself and we establish an approximate analytic expression of the time-delay of the main-field arrival, which fits fairly well the result obtained by numerically solving the Maxwell-Bloch equations.
