We report experimental studies of bright-state polaritons of four-wave mixing (FWM) and six-wave mixing (SWM) signals through cascade nonlinear optical parametric amplification processes in an atom-cavity composite system for the first time. Also, the coexisting cavity transmission modes of parametrically amplified FWM and SWM signals are observed. Finally, electromagnetically induced absorption by the FWM cavity modes in the probe beam is investigated. The investigations can find potential applications in multi-channel narrow-band long-distance quantum communication.
我们首次在原子-腔复合系统中通过级联非线性光参量放大过程报告了四波混频（FWM）和六波混频（SWM）信号的亮态极化激元的实验研究。此外，还观察到参量放大 FWM 和 SWM 信号的共存腔传输模式。最后，研究了探测光束中 FWM 腔模式的电磁感应吸收。这些研究在多通道窄带长距离量子通信中有潜在的应用。
