超光速脉冲通过相位共轭镜的传输
Superluminal pulse transmission through a phase-conjugating mirror
摘要：
我们从理论上分析了波包通过相位共轭镜的传输，并表明，一个适当选择的输入脉冲的传输是超光速的，即脉冲的峰值出现在镜子之前的时间，它需要在真空中旅行相同的距离。这种脉冲整形效应可以直接归因于构成反射镜的非线性介质中的色散关系。因此，第一次在光学相位共轭和超光速行为之间建立了联系。由于相位共轭镜具有额外的放大能力，它是实验观测快子信号的最有希望的候选者。
英文摘要：
We theoretically analyze wave packet transmission through a phase-conjugating mirror and show that the transmission of a suitably chosen input pulse is superluminal, i.e. the peak of the pulse emerges from the mirror before the time it takes to travel the same distance in vacuum. This pulse reshaping effect can be attributed directly to the dispersion relation in the nonlinear medium constituting the mirror. Thus, for the first time a connection is laid between optical phase conjugation and superluminal behavior. In view of its additional amplifying ability, a phase-conjugating mirror is a most promising candidate for an experimental observation of tachyonic signatures.
