For the first time, we experimentally and theoretically research about the probe transmission signal (PTS), the reflected four wave mixing band gap signal(FWM BGS) and fluorescence signal (FLS) under the double dressing effect in an inverted Y-type four level system. FWM BGS results from photonic band gap structure. We demonstrate that the characteristics of PTS, FWM BGS and FLS can be controlled by power, phase and the frequency detuning of the dressing beams. It is observed in our experiment that FWM BGS switches from suppression to enhancement, corresponding to the switch from transmission enhancement to absorption enhancement in the PTS with changing the relative phase. We also observe the relation among the three signals, which satisfy the law of conservation of energy. Such scheme could have potential applications in optical diodes, amplifiers and quantum information processing.
首次在倒Y型四能级系统的双修饰效应下，对探测传输信号（PTS）、反射四波混频带隙信号（FWM BGS）和荧光信号（FLS）进行了实验和理论研究。FWM BGS源于光子带隙结构。我们证明了PTS、FWM BGS和FLS的特性可以通过修饰光束的功率、相位和频率失谐来控制。在我们的实验中观察到，随着相对相位的变化，FWM BGS从抑制转变为增强，这对应于PTS中从传输增强到吸收增强的转变。我们还观察到这三个信号之间的关系，它们满足能量守恒定律。这种方案在光二极管、放大器和量子信息处理方面可能具有潜在应用。
