论文摘要
我们从理论上和数字上研究热噪声对向后刺激的脉冲刺激布里鲁因散射（SBS）的影响。使用随机演算和数值方法的组合，我们得出了一个理论模型，可用于定量预测噪声测量值。我们研究光脉冲配置，包括泵和Stokes场的输入功率，脉冲持续时间和交互时间如何影响输出Stokes Field中的噪声。我们研究了光损失和波导长度的噪声的影响，我们发现，对于波导性质和脉冲参数的特定组合，可以显着提高或减少信号 - 噪声比。
We theoretically and numerically study the effects of thermal noise on pulses in backwards Stimulated Brillouin Scattering (SBS). Using a combination of stochastic calculus and numerical methods, we derive a theoretical model that can be used to quantitatively predict noise measurements. We study how the optical pulse configuration, including the input powers of the pump and Stokes fields, pulse durations and interaction time, affects the noise in the output Stokes field. We investigate the effects on the noise of the optical loss and waveguide length, and we find that the signal-to-noise ratio can be significantly improved, or reduced, for specific combinations of waveguide properties and pulse parameters.
