提出了一种名为“欺骗”四波混频（SFWM）的方案，其中由共传播泵浦和信号的跳动诱导的动态折射率光栅能够调制布拉格光栅（BG）以在未受扰动的BG带隙两侧产生额外的反射峰（ARPs）。当位于ARPs波长的探测波反向传播时，它在跟踪信号数据信息的同时被诱导的ARPs反射，但在新的波长上。在众所周知的FWM中，诱导动态折射率光栅调制光子以产生新频率的波，而SFWM的不同之处在于，动态折射率光栅是在非线性BG中产生的，以激发反射光谱中原始BG带隙两侧的ARPS。这一根本性的差异使SFWM避免了传统FWM所要求的严格相位匹配的固有缺点，并允许具有调制格式透明和超宽转换范围的新型全光波长转换，这是下一代全光网络的主要优势。
A scheme named “spoof” four wave mixing (SFWM) is proposed, where a dynamic refractive index grating induced by the beating of the co-propagating pump and signal is able to modulate a Bragg grating (BG) to create additional reflective peaks (ARPs) at either side of the unperturbed BG bandgap. When a probe wave located at the wavelength of ARPs is counter-propagating, it is reflected from the induced ARPS while tracking the signal data information but at the new wavelength. In contrast to the well-known FWM, where the induced dynamic refractive index grating modulates photons to create a wave at a new frequency, the SFWM is different in that the dynamic refractive index grating is generated in a nonlinear BG to excite ARPS at either side of the original BG bandgap in reflection spectrum. This fundamental difference enable the SFWM to avoid the intrinsic shortcoming of stringent phase matching required in the conventional FWM, and allows novel all-optical wavelength conversion with modulation format transparency and ultrabroad conversion range, which represents a major advantage for next generation of all-optical networks.
