基于光纤中SRS效应的全光波长转换

All-optical wavelength conversion based on stimulated Raman scattering in optical fiber

  • 摘要: 提出利用光纤中非线性效应受激喇曼散射(stimulated Raman scattering, SRS)实现波长转换的原理方案和相应的理论分析模型,并进行实验验证,将经过放大后的信号光和连续探测光同时注入光纤,在光纤中进行SRS放大,实现信号之间的转换。结果表明:利用SRS可实现波长转换,可实现跨几个THz的波长之间的转换。得到最大转换效率和消光比分别为-17.3 dB和15.7 dB。通过改变探测光的波长,可实现相隔几个THz光信号的全光波长转换和可调谐波长转换。

     

    Abstract: A novel all-optical wavelength conversion scheme based on stimulated Raman scattering (SRS) in optical fiber and the corresponding model were theoretically proposed and experimentally demonstrated. The amplified signal light and continuous probe light were injected into fiber simultaneously and the wavelength conversion were achieved between the two lights. The results show that SRS can be used to achieve wavelength conversion and realize the conversion between the wavelength across several THz. The maximum conversion efficiency and optimum extinction ratio are -17.3 dB and 15.7 dB respectivly. By changing the wavelength of probe light,the all-optical wavelength conversion and tunable wavelength conversion seperated several THz can be realized.
