基于扩展相位匹配的光谱相位共轭
Spectral phase conjugation via extended phase matching
摘要：
结果表明，在适当的第二类扩展相位匹配和短二次谐波脉冲泵浦下，共传三波混频参量过程可以实现光谱相位共轭和参量放大，表现出类似于后向波振荡的阈值行为。该过程还在海森堡图像中进行了分析，该图像预测了与Kuzucu等人报道的实验结果一致的自发参量下转换率[Phys.Rev.Lett. 94，083601（2005）]。可以设想在光通信、信号处理和量子信息处理中的应用。
英文摘要：
It is shown that the copropagating three-wave-mixing parametric process, with appropriate type-II extended phase matching and pumped with a short second-harmonic pulse, can perform spectral phase conjugation and parametric amplification, which shows a threshold behavior analogous to backward wave oscillation. The process is also analyzed in the Heisenberg picture, which predicts a spontaneous parametric down conversion rate in agreement with the experimental result reported by Kuzucu et al. [Phys. Rev. Lett. 94, 083601 (2005)]. Applications in optical communications, signal processing, and quantum information processing can be envisaged.
