We propose and experimentally demonstrate that the intensity noise correlation and the noise level of intensity-difference and intensity-sum in Stokes and anti-Stokes channel can be well controlled by the relative nonlinear phase in spontaneous parametric four-wave mixing process. By modulating the relative nonlinear phase, including self-phase modulation and cross-phase modulation, switching the correlation into anti-correlation and the relative intensity noise level between the intensity-difference and intensity-sum are realized. We also show that the variation tendencies of the relative intensity noise level and the corresponding intensity fluctuations correlation are in accordance with each other.
我们提出并实验验证了在受激参量四波混频过程中,通过控制相对非线性相位可以有效地控制斯托克斯和反斯托克斯通道中强度差和强度和的强度噪声相关和噪声水平。通过调制相对非线性相位,包括自相位调制和交叉相位调制,我们实现了相关从正相关到反相关的切换以及强度差和强度和之间的相对强度噪声水平的变化。我们还表明,相对强度噪声水平的变化趋势与相应的强度波动相关是一致的。
