摘要
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。
Multi wavelength conversion was simultaneously achieved by using nonlinear optical loop mirror (NOLM). The maximum separation of the wavelength conversion between the control laser and the signal laser is larger than 25 nm. In the system, the gain switched distributed feed back laser diode is used as the control pulse with the pulse width of 20 ps, the spectrum sliced fiber amplifier light source is used as the signal lasers with multi wavelength output. The performance of the converted signal with different wavelength depends on the control optical power or the direction of the polarization controller in NOLM.
