对光波携带的信号进行全光学操纵是有吸引力的，因为直接控制光可以更有效，允许多种信号格式，并且还可以证明最具成本效益。我们实现了一种新的超快光开关方案，使用非常小的控制能量，依赖于饱和光纤参量放大器的使用。大约19 aJ（150光子）的控制脉冲能量需要50%的消光信号，这是三到四个数量级小于其他全光开关演示。这允许考虑新颖的实用方法来实现用于电信和其他应用的全光开关器件和全光子系统。
All-optical manipulation of signals carried by lightwaves is attractive because controlling the light directly can be more efficient, allows a multitude of signal formats, and can also prove most cost effective. We implemented a novel scheme for ultrafast optical switching using very small control energy that relies on the use of a saturated fiber-optic parametric amplifier. Approximately 19 aJ (150 photons) of control pulse energy was needed for 50% extinction of the signal which is three to four orders of magnitude smaller than in other all-optical switching demonstrations. This allows the consideration of novel practical approaches to implement all-optical switching devices and all-optical subsystems for telecommunications and other applications.
