利用非线性光学环路镜 (NOL M)成功地实现了多个波长的同时变换。最大波长变换间距大于 2 5nm。实验系统中采用增益开关分布反馈半导体激光器 (GS DFB- L D)产生的超短光脉冲作为控制光 ,频谱分割法得到多波长激光作为信号光。改变控制光的输入功率或非线性光学环路镜中的偏振控制器的偏振方向能够改变不同变换波长信号的性能 The simultaneous conversion of multiple wavelengths is successfully achieved with a nonlinear optical loop mirror (NOL M). Maximum wavelength conversion spacing greater than 25nm. In the experimental system, an ultra-short optical pulse generated by a gain switch distributed feedback semiconductor laser (GS DFB-LD) is used as the control light, and a multi-wavelength laser is obtained as the signal light by the spectrum division method. Changing the input power of the control light or the polarization direction of the polarization controller in the nonlinear optical loop mirror can change the performance of the different wavelength converted signals
