【摘要】 最先利用非线性光学环路镜 (NOLM)成功地将 2 5Gbit/s的归零码光脉冲同时变换到不同的两个波长上 .最大波长变换间距为 35nm .实验系统中采用增益开关分布反馈半导体激光器 (GSDFB LD)产生的超短光脉冲作为控制光 ,采用分布反馈半导体激光器 (DFB LD)和波长可调激光器作为信号光 .首次在 1 5 5 μm波长段利用非线性光学环路镜进行波长变换过程时观测到了反相波长变换和脉冲畸变现象 .更多还原

【Abstract】 Two channel wavelength conversion for 2 5Gbit/s,return to zero optical Pulse based on nonlinear optical loop mirror was achived for the first time.The maximum separation between the control laser wavelength and the signal laser wavelength is 35nm.In this system,GS DFB LD is used as the control pulse with the pulse width of 20ps,DFB LD and wavelength tunable laser are used as signal lasers.The phase wavelength conversion and pusle degradation were observed for first time at the wavelength of 1 550μm.更多还原
