利用光纤中的布里渊慢光效应实现了四波混频过程中相位匹配条件的全光控制。在波长转换方案中，采用对向传播受激布里渊散射（SBS）泵浦来控制四波混频泵浦的相速度。实验结果和理论模拟表明，SBS控制的波长转换效率相差20 dB。
All-optical control of the phase-matching condition in four-wave mixing (FWM) processes is demonstrated using the Brillouin slow-light effect in optical fibers. A counterpropagating stimulated Brillouin scattering (SBS) pump has been used to control the phase velocity of the FWM pump in a wavelength conversion scheme. Both experimental results and theoretical simulations show an SBS-controlled 20 dB difference on the wavelength conversion efficiency.
